Which one of the following will NOT produce carbon dioxide on reacting with an aqueous solution of hydrochloric acid?

Limestone

Quick lime

Chalk

Marble

Explanation:

In the given options, marble, limestone, and baking soda are all either metal carbonates or bicarbonates. All these when react with a dilute acid then they produce carbon dioxide. Whereas lime which is calcium oxide when react with a dilute acid then they do not produce carbon dioxide. For example,
CaO + dil. 2HCI —> CaCl₂ + H₂O
Thus, lime when reacts with an acid then it produces salt and water but it does not produce carbon dioxide.
