How do you write an equation for the reaction between zinc metal and hydrochloric acid (aqueous) producing zinc chloride (aqueous) and hydrogen gas?

1 Answer



The net reaction is #Zn(s)+2H^+(aq) ->Zn^(2+)(aq)+H_2(g)#
The #Cl^-# ions are spectators - they don't change.

This experiment includes the reaction of zinc with hydrochloric acid. The experiment compares reactivity of three metals; magnesium, zinc and copper. The video includes a discussion of writing balanced equations for all the observed reactions.
