Question

Marble chips reacts with a solution to produce a gas which turns lime water milky. So the solution contains:

• A. H₂SO₄
• B. K₂SO₄
• C. Na₂SO₄
• D. K₂SO₄

Answer 1

The explanation for the correct option is

Option(A) H₂SO₄

• Calcium carbonate reacts with sulphuric acid to form calcium sulsulfated carbon dioxide which turns lime water milky.

$CaC{O}_3\left(s\right)+H_{2}S{O}_4\left(aq\right)⟶CaS{O}_4\left(s\right)+C{O}_2\left(g\right)+H_{2}O$

Hence, Option(A) $H_{2}S{O}_4$ is the correct option. hence, Marble chips react with a solution to produce a gas that turns lime water milky. So the solution contains $H_{2}S{O}_4$
