Question

Consider the reaction when aqueous solutions of potassium hydroxide and zinc iodide are combined. The net ionic equation for this reaction is:

Answer 1

Molecular equation:

2KOH(aq) + ZnCl₂(aq) ==> 2KCl(aq) + Zn(OH)₂(s)

Since a solid is formed, and all other species are aqueous, we have the following NIE...

Zn²⁺(aq) + 2OH^-(aq) ==> Zn(OH)₂(s)
