Solution
A white precipitate will be formed if we add common salt solution to AgNO3 solution.
Explanation:
Common salt is sodium chloride (NaCl). When it is mixed with a silver nitrate (AgNO3) solution, a double displacement reaction occurs. The silver ions (Ag+) combine with chlorine ions (Cl−) to form an insoluble white precipitate of silver chloride (AgCl).
\[\ce{AgNO3_{(aq)} + NaCl_{(aq)} -> AgCl_{(s)}\downarrow + NaNO3_{(aq)}}\]
