Write the net ionic equation for the precipitation reaction that occurs when aqueous solutions of chromium(III) bromide and pota
expeople1 [14]

Explanation:

An ionic equation will be the one in which all the participating species will be present as ions.

The given reaction will be as follows.

     CrBr_{3} + K_{2}CO_{3} \rightarrow Cr_{2}(CO_{3})_{3}(s) + KBr

Balancing this equation by multiplying CrBr_{3} by 2 and K_{2}CO_{3} by 3 on reactant side. Whereas multiply KBr by 6 on product side.

      2CrBr_{3} + 3K_{2}CO_{3} \rightarrow Cr_{2}(CO_{3})_{3}(s) + 6KBr

Hence, the net ionic equation will be as follows.

       2Cr^{3+}(aq) + 3CO^{2-}_{3}(aq) + 6K^{+} + 6Br^{-} \rightarrow Cr_{2}(CO_{3})_{3}(s) + 6K^{+} + 6Br^{-}

As both K^{+} and Br^{-} are spectator ions. Hence, the net ionic equation will be as follows.

     2Cr^{3+}(aq) + 3CO^{2-}_{3}(aq) \rightarrow Cr_{2}(CO_{3})_{3}(s)
