To a buffer solution of CH(3),COOH and C...

To a buffer solution of `CH_(3),COOH` and `CH_(3),COONa`, some HCI is added. Then the reaction involved is

A

`CH_3 COOH +OH^(-) to CH_3 COO^(-) +H_2O `

B

`CH_3 COO^(-) +H^(+) to CH_3 COOH`

C

` Na^(+) OH^(-) to NaOH`

D

` CH_3 COO^(-) + Na^(+) to CH_3 COONa`

Text Solution

Verified by Experts

The correct Answer is:
B
HCl is acid
`therefore ` basic `CH_3 COO^(-) ` reacts with it
` CH_3 COO^(-) +H^(+) to CH_3 COOH`
