The net ionic equation contains which of the following species (when balanced in standard form)?

a. 2K+(aq)

b. 2KNO3(aq)

c. No net ionic equation exists for this reaction.

d. 3NO-3(aq)

e. 2Na+(aq)

Answer:

Option c.

No net ionic equation exists for this reaction

Explanation:

The reaction is:

KCl(aq) + NaNO₃(aq) → KNO₃(aq) + NaCl(aq)

In this case they are soluble in water, so as no precipitate is formed there is no net ionic equation.

a. We only have a mol of K⁺

b. We only have a mol of KNO₃

d. We only have a mol of NO₃⁻

3NO³⁻ is an erroneous data

e. We only have a mol of Na⁺
