Zinc reacts with dilute HCl to form zinc chloride and hydrogen gas.
Zn+2HCl→ZnCl2+H2↑
Explanation:
1.The reaction between zinc and hydrochloric acid is Zn + HCl = H2 + ZnCl2. It is a single replacement reaction where zinc metal displaces the hydrogen to form hydrogen gas and zinc chloride , a salt.
2.The reaction is exothermic, and thus the reaction generates heat. When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the reaction.
3.A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.
4.The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound.
