Al(OH)3 is a solid. Therefore is does not dissociate and must be present in the net ionic equation. HCl is aqueous. Therefore it will dissociate into ions. Specator ions should not be included in a net ionic equation. Which ion(s) are spectator(s)?

chloride ion, Cl-.

Explanation:

The reaction between both compounds is given as;

Al(OH)3(s) + 3HCl(aq) → AlCl3(aq) + 3H2O(l)

The ionic equation is given as;

Al(OH)3(s) + 3H+ + 3Cl- → Al3+  + 3Cl- + 3H2O(l)

Spectator ions should not be included in a net ionic equation.

The spectator ion in the ionic equation is the chloride ion, Cl-.
