Silver ions can be precipitated from aqueous solutions by the addition of aqueous chloride:
Ag⁺(aq) + Cl⁻ (aq) → AgCl(s)
Silver chloride is virtually insoluable in water so that the reaction appears to go to completion. How many grams of solid NaCl must be added to 25 mL of 0.366 M AgNO₃ solution to completely precipitate the silver?
