The answer is that "Ag+ ion combines with the chloride ion to form a precipitate".
Silver chloride is formed in the form of precipitates, Ag⁺ is a cation and Cl⁻ is an anion so both ions attract each other and combines to form AgCl.
The equation for the ionic reaction that occurs is;
Ag⁺(aq)+Cl⁻(aq)→AgCl(s)
