Question

Identify the spectator ions in this reaction. Check all that apply.

Answer 1

Answer:

$Na^+\text{ and }CO_3^-$

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.

Only the species which are present in aqueous state dissociate.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The complete ionic equation in separated aqueous solution will be,

$2H^+_{(aq)}+CO_3^-_{(aq)}+2Na^+_{(aq)}+2OH^-_{(aq)}\rightarrow 2H_2O_{(l)}+CO_3^-_{(aq)}+2Na^+_{(aq)}$

In this equation the species present are, $Na^+\text{ and }CO_3^-$ are the spectator ions.

Hence, the net ionic equation contains specie is  

$2H^+_{(aq)}+2OH^-_{(aq)}\rightarrow 2H_2O_{(l)}$

Answer 2

The two correct answers are:

CO32–

Na+

I hope you get the day you deserve :)
