Hello Chetan

Acidic Buffers are solutions that have a ph elow 7 and contain a weak acid and one of its salts. 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.

A buffer solution  is an aqueous solution consisting of a mixture of a weak acid and its conjugate base , or vice versa.

I hope your question has been answered properly.

All the best !

Hi Chetan,

Acidic buffers are the solutions with pH value below 7 and they constitute of some weak acids like acetic acid etc and one salt of this acid.

Basic buffers are the solutions with pH value above 7 and contain some weak bases like Ammonia etc and one salt of this base.

I hope this information helps you.

Good Luck!
