Buffer solution have constant acidity an...

Buffer solution have constant acidity and alkalinity because :
1. these give unionised acid or base on reaction with added acid and bases
2. acids and alkalies in these solution are shielded from attack by other ions
3. they have large excess of `H^(+) or OH^(-) ` ions
4. they have fixed value of pH

A

They have large excess of `H^(+) or OH^(-)` ions

B

They have fixed value of pH

C

These give unionised acid or base on reaction with added acid or alkali

D

Acids and alkalies in these solutions are shielded from attack by other ions

Text Solution
