What produces hydrogen ions in a solution?
An acid produces hydrogen ions in solution because it reacts with the water molecules by giving a proton to them. When hydrogen chloride gas dissolves in water to produce hydrochloric acid, the hydrogen chloride molecule gives a proton (a hydrogen ion) to a water molecule.
What is the loss of hydrogen called?
The most likely place you will come across them is in organic chemistry. Oxidation is loss of hydrogen. Reduction is gain of hydrogen. Notice that these are exactly the opposite of the oxygen definitions. For example, ethanol can be oxidised to ethanal: You would need to use an oxidising agent to remove the hydrogen from the ethanol.

Defining potential The potential of an individual is measured by a method called Potential Analysis that assesses their abilities and skills, and whether or not they have the ability to develop those skills further. This is accomplished through a series of tests to assess their personality and skills.
What is hydrogen used for?
Almost all hydrogen produced is used for refining fossil fuels, producing fertilizer, and treating metals. However, thanks to the use of hydrogen-filled fuel cells, the transport industry is starting to implement the cleaner fuel source as well. Fuel cell electric vehicles (FCEVs) harness the energy of hydrogen to power the motor. High-pressure fuel tanks store the hydrogen, which is then delivered to a fuel cell, where it combines with oxygen to produce electricity. Stored as a compressed gas, with a pressure rating of 5000 to 10000 pounds per square inch (psi), hydrogen gas – like petroleum – is extremely flammable. Unlike traditional fuel, however, it is odorless and colorless, and requires special sensors to detect leaks. When transported, hydrogen gas is also costly and bulky. Yet while these challenges have limited the growth of hydrogen technologies, many industries rely on its fuel cells. Along with light-duty commercial FCEVs, hydrogen fuel cells appear in a variety of machines and vehicles. Buses, forklifts, and ground support equipment, as well as other various stationary applications, use hydrogen as an environmentally friendly power source.
How is hydrogen produced?
Modern hydrogen production can involve various methods. The four main sources for hydrogen include natural gas, oil, coal, and water, with steam reforming being the most popular hydrogen production method. Steam reforming offers an effective solution for producing hydrogen; however, it relies on natural gas. Heating the gas to extreme temperatures in a sealed atmosphere, steam reforming causes an endothermic reaction that breaks up the methane molecules, leaving carbon monoxide and hydrogen. One ton of hydrogen produced through steam reforming, however, generates nine to twelve tons of carbon dioxide as a byproduct. Coal gasification, another method for hydrogen production, uses steam and gases to extract a mixture of hydrogen and carbon monoxide from coal, with the coal-derived hydrogen gas being suitable as a fuel alternative. The drawback to both of these methods is that they still release pollutants into the atmosphere. To reduce emissions, industries are looking for more efficient ways to produce hydrogen, such as electrolysis.
How many hydrogen fueling stations are there in California?
While FCEVs have tanks to store hydrogen gas, drivers may still struggle to find hydrogen fueling stations. To address this problem, California has been investing heavily in hydrogen fueling infrastructure. The state has at least 40 public fueling stations and has plans to open 20 more. Meanwhile, through 2024, the California Energy Commission has allocated up to $20 million per year to fund the construction of additional filling stations, with the goal to have at least a hundred hydrogen fueling stations available to retail customers (CAFCP, 2018). Outside of California, fueling stations are primarily privately owned, used to refuel transport vehicles or to deliver hydrogen gas to other facilities. And while most of today’s electric vehicles use all-electric batteries instead of hydrogen fuel cells, if other states follow California’s lead, the auto industry will have more incentive to manufacture FCEVs.
Does Germany have natural gas?
Reducing the massive costs that would come with building new infrastructure, Germany hopes to gradually reduce its dependence on natural gas, though experts predict natural gas will remain vital for generating German electricity for many years yet.
Is hydrogen gas safe?
It can be used as an alternative fuel for vehicles, heating, and electricity. Hydrogen is completely safe for the environment after it is produced, and a hydrogen fuel cell simply releases water and steam. The chemical element is available in water and organic matter, making it a renewable resource. However, the key obstacle to the efficiency and sustainability of hydrogen as an alternative fuel is the production process. As of today, 95 percent of hydrogen is still produced using steam reforming, releasing carbon monoxide and carbon dioxide into the atmosphere. These greenhouse gases contribute to climate change, limiting the primary benefit of hydrogen gas. While, after production, hydrogen gas can be used without releasing emissions, the emissions released during production still currently offset the benefits to the environment.
Why is hydrogen used as a fuel?
However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft . Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future.

How to measure hydrogen ion concentration?
However, it is possible to measure the concentration of hydrogen ions directly, if the electrode is calibrated in terms of hydrogen ion concentrations. One way to do this, which has been used extensively, is to titrate a solution of known concentration of a strong acid with a solution of known concentration of strong alkaline in the presence of a relatively high concentration of background electrolyte. Since the concentrations of acid and alkaline are known, it is easy to calculate the concentration of hydrogen ions so that the measured potential can be correlated with concentrations. The calibration is usually carried out using a Gran plot. Thus, the effect of using this procedure is to make activity equal to the numerical value of concentration.
Which plant is pH dependent?
pH-dependent plant pigments that can be used as pH indicators occur in many plants, including hibiscus, red cabbage ( anthocyanin ), and grapes ( red wine ). The juice of citrus fruits is acidic mainly because it contains citric acid. Other carboxylic acids occur in many living systems. For example, lactic acid is produced by muscle activity. The state of protonation of phosphate derivatives, such as ATP, is pH-dependent. The functioning of the oxygen-transport enzyme hemoglobin is affected by pH in a process known as the Root effect .

How to measure pH?
Indicators may be used to measure pH, by making use of the fact that their color changes with pH. Visual comparison of the color of a test solution with a standard color chart provides a means to measure pH accurate to the nearest whole number. More precise measurements are possible if the color is measured spectrophotometrically, using a colorimeter or spectrophotometer . Universal indicator consists of a mixture of indicators such that there is a continuous color change from about pH 2 to pH 10. Universal indicator paper is made from absorbent paper that has been impregnated with universal indicator. Another method of measuring pH is using an electronic pH meter .

The pH scale is traceable to a set of standard solutions whose pH is established by international agreement.
Where is hydrogen found?
In New Caledonia, where the Energy Observer ship is currently moored, we can find White hydrogen, the naturally occurring hydrogen. This type of hydrogen is not created by humans, but is found in its natural form, as a free gas, either in layers of the continental crust, deep in the oceanic crust, in volcanic gases, in geysers or in hydrothermal systems. Hydrogen seems to be present in a wide range of rock formations and geological regions.
How does hydrogen come from?
Today, 95% of man-made hydrogen comes from steam reforming, a technique with a great efficiency, but a disastrous carbon footprint. On the other hand, electrolysis creates hydrogen from renewable energies, but loses about two thirds of the energy input in the production process. Natural hydrogen is now being seen as a promising carbon-free and abundant energy-source that requires minimal infrastructures for its exploitation (far from the requirements of oil wells). Due to the lack of dedicated research thus far, it is hard to evaluate the white hydrogen resources in the world. But since march 2021, the initiative EarthH2 is helping scientists and industrialists join forces and together increase the current knowledge on the topic of natural hydrogen. A hydrogen future in white and green could help us transition to carbon-free energies, for the better of the earth and mankind.

Is hydrogen a gas?
Once considered a rare occurrence as a free gas, recent comprehensive reviews show that hydrogen is in fact much more widespread in nature than previously thought. The misconception of free hydrogen being rare can be explained in various ways. Firstly, if no one expects to find free hydrogen, no one samples for it. And this is why, even today, sensor systems and analysing technics are not that good at detecting hydrogen. Another factor, hindering natural hydrogen discovery, is the fact that most wells around the world have been drilled in sedimentary layers, where oil and other fossil energy sources are found. However, these rocks are not the most likely places for hydrogen to be abundant. Lastly, hydrogen being the lightest element on earth, it diffuses rapidly in air and other environments and cannot be retained in geological traps for long periods of time.
