What happens when dilute hydrochloric acid is treated with thefollowing and write balanced chemical equation.) Bleaching powder C) Zinc granules) Baking pewderSadaOR

Answer»

Bleaching Powder is calcium Oxychloride. The chemical formula of bleaching powder is CaOCl2.

When bleaching powder reacts with dil. HCl to liberate Cl2 gas,water and Calcium Chloride .

CaOCl2 + 2HCl ----> CaCl2 +Cl2 +H2O.

The reaction betweenzincandhydrochloric acidisZn+HCl= H2 + ZnCl2. It is a single replacement reaction wherezincmetal displaces the hydrogen to form hydrogen gas andzincchloride, a salt.Zincreacts quickly with the acid to form bubbles of hydrogen.
