What does acid rain do to the world?
Acid rain is one of the consequences of air pollution. Gases produced from the burning of fuels react with the oxygen in the air and water vapour, transforming into acids that fall onto the earth's surface as rain. This acidification of the earth and surface water has devastating effects on ecosystems and poses a serious danger to living beings.

Now, acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases that have caused the moisture to become more acidic than normal.
What is the most acidic acid rain?
The most acidic rain in the Solar System is found on the planet Venus, where the working fluid in the cycle of evaporation, condensation and precipitation is a sulphuric acid solution (rather than water, as on Earth).
Is acid rain harmful to humans?
Walking in acid rain, or even swimming in a lake affected by acid rain, is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes. However, when the pollutants that cause acid rain —SO2 and NOX, as well as sulfate and nitrate particles— are in the air, they can be harmful to humans.
Which compound causes 70% of the acid in acid rain?
Sulphuric acid is formed by conversion of sulphur dioxide emitted from power stations, melting processes, home fires, car exhausts and other sources. It contributes about 70% to the overall acidity of deposition.

Can acid rain burn your skin?
Something with a pH value of 7, we call neutral, this means that it is neither acidic nor alkaline. Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this; it is never acidic enough to burn your skin.
Can you drink rain water?
Rainwater can carry bacteria, parasites, viruses, and chemicals that could make you sick, and it has been linked to disease outbreaks. The risk of getting sick from rainwater may be different depending on your location, how frequently it rains, the season, and how you collect and store the rainwater.
What is the pH of milk?
about 6.7 to 6.9Milk — pasteurized, canned, or dry — is an acid-forming food. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it's acid-forming or alkaline-forming.
Does it rain for 7 years on Venus?
Since Venus does not experience rainfall (except in the form of sulfuric acid), it has been theorized that the lightning is being caused by a volcanic eruption.
What is the pH of human blood?
about 7.35 to 7.45The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40.

IMPACT OF ACID RAIN ON FORESTS. Acid rain can dissolve certain more soluble elements from the soil, like aluminum. The dissolved aluminum begins to accumulate and can reach toxic levels as it enters local streams and wetlands. Acid rain also removes important nutrients from the soil, such as calcium, potassium, and magnesium.
Why are historic buildings affected by acid rain?
Because buildings and monuments cannot adapt to changes in the environment, as plants and animals can, historic structures may be particularly affected by acid precipitation. Scientists are studying effective control technologies to limit the emissions from power plants and automobiles that cause acid rain.

How does acid precipitation affect marble and limestone buildings?
Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details.
What determines acidic strength?
Acidic strength depends on various factors including the polarity of H-A bond, size of A, stability of the conjugate base etc.
How much concentration is a concentrated acid?
In general we say a concentrated acid exhibits a concentration of more than 1 mol/L. And diluted acids are below.
Is H2SO4 more acidic than HNO3?
My initial ‘gut feeling’ response is that H2SO4 is more acidic than HNO3. But, people can have opinions for whatever reason that are wrong so I went hunting. Usually acid strength is based on pKas. I went to several sources for the pKa data. Since there different ways to measure pKa, I wanted to find one source that reported both numbers (and found one, PKa data - OChemOnline ). There it states that the pKa for each acid undergoing the reaction shown is:
What does it mean when an acid is concentrated?
In most cases concentrated means a saturated aqueous solution of an acid.
Is HNO3 a strong acid?
I agree with Bakthiyar’s answer below. If you were familiar with the list of 7 strong acids, then you’d know that HNO3 is a strong acid, and HNO2 is a weak acid. Thus, HNO3 would be stronger.
Is H2SO4 an acid rain?
H2SO4 represents approximately 60% of all acid rain with HNO3 at about 25% and HCl 15%. Has to do mainly with the concentration of the gases in the atmosphere and the acids corresponding pKa values. SO2 is present in large quantities due to burning coal and is a strong acid. H2CO3 is NOT considered acid rain, as it is not strong enough and only results in natural rainwater being around a pH of 5.6. Must be below 5.6 to be considered acid rain. Even with CO2 emissions skyrocketing the pH of rainwater will not change much. Ocean water is another story, as its equilibrium pH is closer to 8.3 and additional CO2 will lower its pH.
What happens when an acid dissociates?
When an acid dissociates, the stability of the products can tell you how likely the dissociation can happen . For example, HA -> H+ + A-. If A- is unstable, it’d probably be an unfavorable reaction. In contrast, if A- is stable, then it’d be a favorable reaction due to increased in entropy with dissocation. If A2- is more stable than A1-, then HA2 is probably a stronger acid than HA1.
