A buffer solution can be prepared from a mixture of

A

sodium acetate and acetic acid is water

B

sodium acetate and HCl in water

C

ammonia and ammonium chloride in water

D

ammonia and sodium hydroxide in water

Text Solution

Verified by Experts

The correct Answer is:
ABC
`CH_(3)COOH + CH_(3)COONa= `Buffer solution
` CH_(3)COONa + HCl to CH_(3)COOH + NaCl`
If HCl is taken in limited quantity, final solution will have both `CH_(3)COOH` and `CH_(3)COONa` needed for buffer solution.
Ammonia and ammonium chloride forms basic buffer.
