Hcl and zinc reaction equation
WebMar 21, 2024 · The reaction of Zinc (Zn) with hydrochloric acids (HCl) is depicted by the following equation: Zn (s) + 2H+ (aq) + 2Cl- (aq) – Zn2+ (aq) + 2Cl- (aq) + H2 (g) … WebJan 14, 2016 · The products of the reaction are aqueous zinc chloride and hydrogen gas. Now, as you can see from the balance chemical equation, a 1:color(red)(2) mole ratio exists between the two reactants. This tells you that in order for the reaction to take place, you need to have twice as many moles of hydrochloric acid as you do of zinc metal.
