Answer: [tex]Cl^-(aq)[/tex] ions are present in the complete ionic equation
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical reaction will be:
[tex]KCl(aq)+NaNO_3(aq)\rightarrow NaCl(aq)+KNO_3(aq)[/tex]
The complete ionic equation can be written in terms of ions as:
[tex]K^+(aq)+Cl^-(aq)+Na^+(aq)+NO_3^-(aq)\rightarrow Na^+(aq)+Cl^(aq)+K^+(aq)+NO_3^-(aq)[/tex]
Thus the complete ionic equation contains [tex]Cl^-(aq)[/tex] species.
