Question

which of the following substance will not give carbon on treatment with dilute acid?
a marble b limestone c baking soda d lime

Answer 1

Hello friend...... ✌✌✌✌✌

The answer is Lime .
This is because Lime (Cao) is the base that reacts with a dilute acid such as HCI to form a salt called calcium chloride. It is an exothermic reaction and releases water but no carbon dioxide. Mable or limestone (CaCO3) or baking soda (NaHCO3) react with HCl to release CO2
