Marble chips reacts with a solution to produce a gas which turns lime ...
Reaction between Marble chips and Solution
When Marble chips are added to a solution, a gas is produced which turns lime water milky. This reaction is a classic example of an acid-base reaction where an acid reacts with a base to produce a salt and water.
Identification of Solution
The question asks us to identify the solution which is reacting with the Marble chips. We know that the gas produced turns lime water milky. Lime water is a solution of Calcium Hydroxide (Ca(OH)2) in water. When Carbon dioxide (CO2) is passed through lime water, it reacts with the Calcium Hydroxide to produce Calcium Carbonate (CaCO3), which is insoluble and hence turns the solution milky.
The equation for this reaction is:
Ca(OH)2 + CO2 → CaCO3 + H2O
Since the gas produced by the reaction between Marble chips and the solution turns lime water milky, we can conclude that the solution is acidic and contains Carbonic acid (H2CO3). This is because when Carbonic acid reacts with Calcium Hydroxide, it produces Calcium Carbonate and water, which turns the lime water milky.
The equation for this reaction is:
H2CO3 + Ca(OH)2 → CaCO3 + 2H2O
Out of the options given, only option B, H2SO4, is an acid. Hence, the correct answer is option B.

When calcium carbonate react with sulphuric acid it gives calcium sulphate + water + carbon dioxide
and after that there is a gas which evolved after the reaction which is carbon dioxide and it turns milky in colour
