When Zinc is added to dilute solution of hydrochloric acid, then hydrogen gas is evolved and zinc chloride is formed. Zinc cholride is soluble in water. The conformation of reaction can be deduced from bubble formation. These bubbles are produced due to hydrogen gas formation. The chemical rreaction can shown as...
Zn + HCl(aq) = ZnCl2 (aq) + H2 (g)

Cool Pav is close. Zn does not react with liquid water, yet does react with acids to make H2 gasoline and a answer of ZnCl2. ZnCl2 is soluble in water and exists as Zn2+ ions and Cl- ions. ZnCl2 isn't black, neither is it a solid. you will specifically situations see some black debris in the answer as zinc dissolves. Chalk this as much as the impurities is advertisement zinc.
