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. |
