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
Zn(s) + 2NaOH(aq) + 2H2O(I) = Na2Zn(OH)4(aq) + H2(g)
Formation of sodium zincate and hydrogen gas. The sodium hydroxide solution need to be concentrated and the mixture warmed for the reaction to go well
