A solution of silver chlorate reacts with a solution of lithium iodide.

Anettt [7]

Answer: $Ag^+(aq)+I^-(aq)\rightarrow AgI(s)$

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.

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

$AgClO_3(aq)+LiI(aq)\rightarrow AgI(s)+LiClO_3(aq)$

The complete ionic equation is:

$Ag^+(aq)+ClO_3^-(aq)+Li^+(aq)+I^-(aq)\rightarrow AgI(s)+Li^+(aq)+ClO_3^-(aq)$

The ions which are present on both the sides of the equation are lithium and chlorate ions. and hence are not involved in net ionic equation.

Thus the net ionic equation is:

$Ag^+(aq)+I^-(aq)\rightarrow AgI(s)$
