For the buffer solution containing nh4oh
WebJun 19, 2024 · The ability of a buffer solution to resist large changes in pH has a great many chemical applications, but perhaps the most obvious examples of buffer action are to be found in living matter. If the pH of human blood, for instance, gets outside the range … WebN H 4 O H ( a q) ⇒ N H 4 ( a q) + + O H ( a q) -. This solution acts as a basic buffer and maintains its pH around 9.25. It resists the change in pH on the addition of a small amount of acid or alkali. This can be explained as below: Upon adding a small amount of HCl to this solution, H + ions of HCl get neutralized by OH – ions already ...
