Write the TOTAL IONIC EQUATION between zinc and hydrochloric acid.
Andreyy89

Answer : The net ionic equation will be,

Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced ionic equation between zinc and hydrochloric acid will be,

Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)

The ionic equation in separated aqueous solution will be,

Zn(s)+2H^+(aq)+2Cl^-(aq)\rightarrow Zn^{2+}(aq)+2Cl^-(aq)+H_2(g)

In this equation, Cl^- is the spectator ion.

By removing the spectator ion from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)
