When Limestone Reacts with Dilute Hcl?

When a piece of limestone reacts with dilute HCl, a gas X is produced. When gas X is passed through lime water then a white precipitate Y is formed. On passing excess of gas X, the white precipitate dissolves forming a soluble compound Z.

When a piece of limestone reacts with dilute HCl which gas is produced?

(i) When a piece of limestone or calcium carbonate is treated with dilute hydrochloric acid, carbon dioxide gas (CO2, here given as X) is produced.

What type of reaction is limestone and hydrochloric acid?

Gas-forming reactions

An example of a gas-forming reaction is that which occurs when a metal carbonate such as calcium carbonate (CaCO3, the chief component of limestone, seashells, and marble) is mixed with hydrochloric acid (HCl) to produce carbon dioxide.
