a solution contains equal amounts of ammonia and ammonium chloride, and is buffered at a pH of 9.25. Which action will most strengthen the buffering capacity at this pH?
Doubling the amounts of both ammonia and ammonium chloride is the action
that will most likely strengthen the buffering capacity of a solution that contains
equal amounts of ammonia and ammonium chloride, and is buffered at a pH of 9.25.
