Question

What happens when sulphuric acid is added to marble chips?

Answer 1

Answer:

Explanation:

So when calcium carbonate reacts with sulphuric acid, it forms water, carbon dioxide and calcium sulphate. The reaction between sulfuric acid and calcium carbonate is somewhat similar to the reaction with sodium bicarbonate way - carbon dioxide bubbles out, and the salt is left behind is calcium sulfate.

Answer 2

A brisk effervescence of Carbon Dioxide is observed when sulphuric acid is added to marble chips.

- The marble chips are made up of Calcium carbonate.

- When we add sulphuric acid, they form water, calcium sulphate and brisk effervescence of carbon dioxide gas.

- The balanced chemical reaction between sulfuric acid and calcium carbonate is given as:

CaCO3 (s) + H2SO4 (l) → CaSO4 (s) + H2O (l) + CO2 (g)
