Write the balanced COMPLETE ionic equation for the reaction when aluminum nitrate and sodium phosphate are mixed in aqueous solution. If no reaction occurs, simply write only NR.

Answer 1

Aluminum nitrate = Al(NO₃)₃

Sodium phosphate = Na₃PO₄

The complete molecular equation is:

Al(NO₃)₃(aq) + Na₃PO₄(aq) ==> AlPO₄(s) + 3NaNO₃(aq) ... balanced molecular equation

Since a precipitate is formed and all other compounds are soluble, we only need to include the ions that participate if forming the precipitate. The balanced net ionic equation is:

Al³⁺(aq) + PO₄^3-(aq) ==> AlPO₄(s) ... balanced net ionic equation
