Write chemical reaction equations to explain how your acetic acid-acetate buffer reacts with both an acid and reacts with a base Pus Magnesiumide 2. Buffer capacity has a rather loose definition, yet it is an important property of buffers. A commonly seen definition of buffer capacity is: "The amount of Hor OH that can be neutralized before the pH changes to a significant degree." Use your data to determine the buffer capacity of Buffer A and Buffer B.

Answer 1

1. Addition of Arid: Hot + Nato - AOH + H₂O + Nat Addition of Base: HOT AGOH AGOTHO Thus the [hot] and [OH-] doesn't increase and the pH remains Constant.
