Procedure

50 mmol benzoic acid is dissolved in 50 mL of methanol. 50 mmol NaOH dissolved in 50 mL water is added slowly to the benzoic acid solution prepared while stirring to obtain sodium benzoate. 50 mmol silver nitrate dissolved in 50 mL water is added to the sodium benzoate solution, and then white precipitate forms fast. The precipitate is washed to remove unreacted silver nitrate and NaOH with water, filtered and washed several times to remove unreacted benzoic acid with methanol. The filtrant white silver benzoate is sensitive to light and should be dried and stored in dark room or under yellow light.
