Question

Write the net ionic equation for this precipitation reaction. Include physical states. ( NH 4 ) 2 CO 3 ( aq ) + Ca ( ClO 4 ) 2 ( aq ) ⟶ CaCO 3 ( s ) + 2 NH 4 ClO 4 ( aq

Answer 1

Answer:

The net ionic equation:

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$

Explanation:

The given chemical reaction is as follows.

$(NH_{4})_{2}CO_{3}(aq)+Ca(ClO_{4})_{2}(aq) \rightarrow CaCO_{3}(s)+2NH_{4}ClO_{4}(aq)$

The total ionic equation is as follows.

$2NH_{4}^{+}(aq)+ CO_{3}^{2-}(aq)+Ca^{2+}(aq)+2ClO_{4}^{-}(aq) \rightarrow CaCO_{3}(s)+2NH_{4}^{+}(aq)+2ClO_{4}^{-}$

Similar ions on the both sides of the reaction will be cancelled.

The remaining reaction is

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$

Therefore, the net ionic reaction is as follows.

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$
