WebThe balanced chemical equation for the reaction is: Zn + 2 HCl ZnCl2 + H2. Therefore, the number of moles of HCl required to react with a certain number of moles of Zn is twice that of Zn. WebZinc metal reacts with hydrochloric acid according to the balanced equation : \mathrm {Zn} (s)+2 \mathrm {HCl} (a q) \longrightarrow \mathrm {ZnCl}_ {2} (a q)+\mathrm {H}_ If a strong base is mixed with a weak acid, the solution will be slightly basic. Zn ( s) + 2 HCl ( aq) ZnCl 2 ( aq) + H 2 ( g) Bases also react with certain metals, like zinc or aluminum, to produce hydrogen gas. Acids react with most metals to form a salt and hydrogen gas. This is a double displacement reaction, so the cations and anions swap to create the water and the salt. The acid and base have neutralized each other, and the acidic and basic properties are no longer present. zinc metal reacts with hydrochloric acid place when (a) dilute sulphuric acid reacts with zinc granules.
