Write the balanced NET ionic equation for the reaction when Al(NO₃)₃ and NaOH are mixed in aqueous solution. If no reaction occurs, simply write only NR.

Answer 1

Al(NO₃)₃(aq) + 3NaOH(aq) ==> Al(OH)₃(s) + 3NaNO₃(aq) ... balanced MOLECULAR equation

From the molecular equation, note that a precipitate is formed. Thus, the NET ionic equation only needs to consider the ions making up the precipitate. The net ionic equation would be...

Al³⁺(aq) + 3OH^-(aq) ==> Al(OH)₃(s) ... balanced NET IONIC equation
