Question

(i) Define buffer solutions?

(ii)What are the types of buffer solutions. Give examples? [1+2]​

Answer 1

Answer:

1) A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. ... Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.

2) Types of Buffer Solutions

Buffers are broadly divided into two types – acidic and alkaline buffer solutions. ... For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75. Alkaline buffers, on the other hand, have a pH above 7 and contain a weak base and one of its salts.
