Question

Define buffer
explain it

Answer 1

Answer:

Explanation:

Buffer is a mixture of weak acid and its salts with conjugate base or weak base and itz salts with conjugate acid which reisitst any change in ph when a small amount of acid or base is added

Answer 2

BUFFER :

A mixture of conjugate acid or conjugate base which resist change in ph when a small amount of strong acid or strong base is added to it.

Buffer Solutions

Buffers are solutions that resist a change in pH on dilution or on addition of small amounts of acids or alkali.

Types of Buffer Solutions

Buffers are broadly divided into two types – acidic and alkaline buffer solutions.

Acidic buffers are solutions that have a pH below 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.

• For example, a mixture of ammonium chloride and ammonium hydroxide acts as a buffer solution with a pH of about 9.25.
