When silver nitrate (AgNO
3
) reacts with sodium chloride (NaCl) a white precipitate of silver chloride (AgCl) is formed which is highly insoluble in water, along with formation of sodium nitrate (NaNO
3
).
Since (AgCl) is insoluble in water it will precipitate out and (NaNO
3
) is soluble in water so it will remain dissolved in the mixture. This reaction is an example of double displacement reaction and it occurs as follows:-
AgNO
3
+ NaCl→AgCl + NaNO
