Answer:

Agâș(aq) +Cl⁻(aq) → AgCl(s)

Explanation:

The questions requires we write the net ionic equation for the reaction between aqueous potassium chloride and aqueous silver nitrate.

Step 1: Writing a balanced equation for the reaction.

  • The balanced equation for the reaction between aqueous potassium chloride and aqueous silver nitrate will be given by;

KCl(aq) + AgNO₃(aq) → KNO₃(aq) +AgCl(s)

  • AgCl is the precipitate formed by the reaction.

Step 2: Write the complete ionic equation.

  • The complete ionic equation for the reaction is given by showing all the ions involved in the reaction.

Kâș(aq)Cl⁻(aq) + Agâș(aq)NO₃⁻(aq) → Kâș(aq)NO₃⁻(aq) +AgCl(s)

  • Only ionic compounds are split into ions.

Step 3: Write the net ionic equation for the reaction.

  • The net ionic equation for a reactions only the ions that fully participated in the reaction and omits the ions that did not participate in the reaction.
  • The ions that are not involved directly in the reaction are known as spectator ions and are not included while writing net ionic equation.

Agâș(aq) +Cl⁻(aq) → AgCl(s)
