What happens when zinc reacts with sulphuric acid?

 Today, you are going to learn  What happens when zinc reacts with sulphuric acid?. The reaction is related to Chemical reactions and equations.

Zinc reacts with Sulphuric acid

When zinc reacts with sulphuric acid, zinc sulphate is formed and hydrogen gas evolved.

The reaction of  Zinc with  dilute sulphuric acid

Zn + H₂SO₄   → ZnSO₄  + H₂↑

Zinc is more reactive hydrogen so Zinc displaced hydrogen from sulphuric acid. This is an example of a displacement reaction.

We can understand  the above reaction by the following  method

 

The Zinc metal becomes Zinc ions (Zn⁺² ) by losing electrons, and reacts to H+ ions and    `\ SO_4^(2-)`   ions formed from Sulphuric acid.

The Zinc ions (Zinc metal functions as a  reducing agent) react with `\SO_4^ (2-)` ions to form  ZnSO4 as salt.

 

Zn⁺² + SO₄^2-  → ZnSO₄

 

The electrons lost by Zinc metal received by the H+ ions from H₂SO₄ to form H₂ gas

 

2(H)+ + 2e-  →H₂

FAQs

1. Why is hydrogen gas released during the reaction?

Ans.- Zinc is more reactive than hydrogen so it displaces hydrogen from sulphuric acid that’s why hydrogen gas is released during the reaction.

2. What other acids can be used to react with zinc?

Ans. – Zinc can react with other acids like HCl, HNO₃, CH₃COOH etc. The reaction depends on the concentration of acids.

3.What is the chemical equation for the reaction between zinc and sulfuric acid?

Ans.- Zn  + H₂SO₄   →ZnSO₄   + H₂

4. What products are formed when zinc reacts with sulphuric acid?

Ans. – Zinc sulphate and hydrogen are the products when zinc reacts with sulphuric acid.

5. What type of reaction is the reaction between zinc and sulfuric acid?

Ans. - Displacement reaction

6. Is zinc sulphate soluble in water?

Ans. – yes, zinc sulphate is highly soluble in water
