Buffer solution have constant acidity and alkalinity because

Asked by admin @ 29/08/2021 in Chemistry viewed by 279 People

Buffer solutions have constant acidity and alkalinity because

(a) these give unionised acid or base on reaction with added acid or alkali.
(b) acids and alkalies in these solutions are shielded from attack by other ions.
(c) they have large excess of H⁺ or OH⁻ ions
(d) they have fixed value of pH

Answered by admin @ 29/08/2021

Buffer solutions resist a change in P H because they react with any added acid or base to give a salt

Option 1)

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