What type of reaction can occur between a metal and an acid?
The reactions of acids with metals are redox reactions. For example, the ionic equation for the reaction of magnesium with hydrochloric acid is: 2H + (aq) + Mg(s) → Mg 2+ (aq) + H 2 (g)
What happens in a reaction between acid and metal?
While exploring what happens when metals come in contact with acids, it is apparent that most, but not all, have some sort of reaction, usually forming hydrogen gas. The result is the production of salts. Hydrochloric Acid Some metals dissolve in this acid and this results in the formation of hydrogen gas and oxidized metal chlorides.
What are products if an acid reacts with a metal?
Key Points
- Acids react with most metals.
- When an acid reacts with a metal, the products are a salt and hydrogen.
- This is the general word equation for the reaction: metal + acid → salt + hydrogen

Is acid and metal a neutralisation reaction?
Acids can be neutralised by metal carbonates In the neutralisation reaction between an acid and a metal carbonate, there are three products. The hydrogen ions (H +) from the acid react with the carbonate ions (CO 3 2-) to form water and carbon dioxide gas. A salt is also produced.

How do group 1 metals react with acids? - Quora
Answer (1 of 2): The name for them as a group (alkali metal) should give a clue as to the answer! All of them react vigorously (if not violently) with strong acids and readily with even weak ones (e.g phenols, acetic acid). Hydrogen gas is given off in the reaction as the other product. Direct re...
How do acids react with metals? + Example - Socratic.org
An acid metal reaction typically results in a salt and the release of Hydrogen gas. An example of is would be Magnesium in Hydrochloric Acid. Mg + 2HCl -> MgCl_2 + H_2 This is a single displacement reaction where the anion from the Acid recombined with the metal to form the salt, in this case Mg^+2 and Cl^-1 forming MgCl_2 and the Hydrogen gas gets released.
Reaction of Metals with Acids | Definition, Examples, Diagrams - Toppr Ask
During the reaction of some metals with dilute hydrochloric acid, following observations were made. (a) Silver metal does not show any change (b) The temperature of the reaction mixture rises when aluminium (Al) is added.

What is the term for a metal or acid reaction?
Metal and acid reactions are called redox reactions, hence the terms reduction and oxidation. A redox reaction is one where an atom, ion or molecule gains or loses electron (s). Oxidation is when electrons are lost. Reduction is when electrons are gained.
What are the reactions of acid and metal?
Acids and metals react in single replacement reactions, which are oxidation-reduction reactions. In this lesson, we will learn about several single replacement reactions involving various metals with hydrochloric acid and sulfuric acid.
What is the salt produced in the reaction of sulfuric acid and zinc chloride?
We get the same outcome in terms of what is oxidized and reduced. Zinc chloride is the salt produced in this reaction. Let's add zinc to sulfuric acid next.
What is the metal that we put in a beaker?
Magnesium. The tiny piece of shiny, gray metal we placed in the beaker is magnesium (Mg), which is supposedly the ninth most common element in the universe. We add hydrochloric acid (HCl) to the beaker. Bubbles start forming immediately, which is a sign a reaction is happening.
Why is magnesium oxidized?
The magnesium atom lost two electrons, therefore it was oxidized. The hydrogen was reduced because it went from having a positive charge as a reactant, to neutral as a product. It gained the two electrons that magnesium lost.
How many electrons did iron lose in the oxidation reaction?
Iron lost 2 electrons (oxidized), and hydrogen gained 2 electrons (reduced) Our prediction is correct! Iron was oxidized, hydrogen was reduced, and the salt produced was iron (II) chloride. The (II) after the iron just tells us how many electrons iron lost. Our last reaction will be with iron and sulfuric acid.
What will happen to iron in hydrochloric acid?
We'll start with iron added to hydrochloric acid, and we will predict the salt produced will be iron chloride .
What happens when hydrogen reacts with oxygen?
Another interesting thing about hydrogen is that it reacts explosively with oxygen if you bring a flame near it. You may remember learning about this in Chapter 4 about the reactions of non-metals with oxygen. The reaction between a large quantity of hydrogen and oxygen in the air produces a beautiful orange fireball and a very loud boom! Do you remember seeing the following diagram?
What is the last reaction to look at?
The last reactions to look at are those between an acid and a metal. At the end of this chapter, there is a short activity on some of the careers in the chemical industry. Although this is not for assessment purposes, if you do not have time to do it in class, we encourage you to encourage or get your learners to do it as a homework activity. Seeing the real world application for what they learn in the classroom is a very important part of the learning process and in discovering what is possible through science and technology.
How much water to add to dilute hydrochloric acid?
To prepare dilute hydrochloric acid solution, slowly and carefully add approximately 100 ml concentrated hydrochloric acid (33% or 11 M) to 900 ml of cold tap water. It is recommended that you wear safety goggles and protective gloves during this step and that you rinse away any acid spills with cold tap water.
Why does hydrogen gas rise up?
When hydrogen gas is released in a reaction it will immediately rise up, because hydrogen is less dense than air. If you filled a balloon with hydrogen, it would float up and you would need to tie a string to it to prevent it from floating away!
How to tell if a gas is hydrogen?
The presence of bubbles signals that a gas is formed during the reaction. To confirm whether the gas is hydrogen, collect a small amount in a test tube. Hold a glowing splint at the opening of the test tube when you release the gas. If the gas ignites with a characteristic 'pop' sound, we will know it is hydrogen.
What is a chemist?
Chemists are people who have studied chemistry and can use their specialist knowledge of chemical reactions to produce new materials and compounds. These could be new medicines, innovative building materials, new fuels that do not harm the environment and many others.
Where does the name hydrogen come from?
The name hydrogen comes from the Greek words 'hydro ' and ' gen ' which means 'water generator' . Let's now investigate the reaction between an acid and a metal. You should listen carefully for this 'pop' sound during the investigation. If you hear it, it will signal the presence of hydrogen gas!
What happens to metals above hydrogen in the reactivity series?
Of the metals above hydrogen, reactivity increases the further up the reactivity series you go . A reaction with dilute sulfuric acid gives a metal sulfate and hydrogen.
What is the reaction of magnesium and sulfuric acid?
Magnesium reacts with dilute sulfuric acid to give a colourless gas, hydrogen, and a colourless solution of magnesium sulfate. Mg(s) + H2SO4(aq) MgSO4(aq) + H2(g) The reaction with dilute hydrochloric acid looks exactly the same, but this time magnesium chloride is produced.
How to make hydrogen in a lab?
Using the zinc and dilute sulfuric acid to make hydrogen in the lab. This is a traditional way of producing small amounts of hydrogen in the lab. Zinc is a bit slow to react with dilute acids in the cold, and a small amount of copper(II) sulfate solution is added to speed up the reaction.
What is the equation for sulfate ions?
The sulfate ions or chloride ions are again spectator ions, and the ionic equation for the two reactions is just like the magnesium reactions. Zn(s) + 2H+(aq) Zn2+(aq) + H2(g) Zinc atoms are losing electrons to make zinc ions. This is oxidation.
What happens when nitrates are reduced?
Instead, when the nitrate ions are reduced, they give oxides of nitrogen - NO or NO2. Which you get depends on the concentration of the acid. You can get hydrogen from very dilute nitric acid with a reactive metal like magnesium, but even in that case you will get some nitrogen oxides formed as well.
What happens when you react with sulfuric acid?
A reaction with dilute sulfuric acid gives a metal sulfate and hydrogen.
How is salt formed?
Remember that a salt is formed when the hydrogen in an acid is replaced by a metal or an ammonium group. Note: Although you are unlikely to meet the problem at this level, you should know that nitric acid behaves differently, for reasons we wil touch on further down this page.
