A buffer solution contains a weak acid HA and A . When small quantity of NaOH is added, to keep `p^(H)` as constant. which of the following reaction takes place?

A

` HA to H^(+) A^(-) `

B

` H^(+) A^(-) to HA`

C

` HA+ OH^(-) to H_2O +A^(-) `

D

`A^(-) +H_2O to HA+ OH^(-) `

Text Solution

Verified by Experts

The correct Answer is:
C
NaOH added is a base hence acid component of the buffter . `HA+ OH^(-) to H_2O +A^(-) `
