Precipitating Sodium Chloride from Its Solution
Description: When concentrated HCl is added to a saturated solution of sodium chloride, a white precipitate forms. When water is added to the mixture, the precipitate redissolves. The addition of HCl shifts the equilibrium of chloride ions in solution.
