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

Options

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`

Answer

B

Explanation

HCl is acid
`therefore ` basic `CH_3 COO^(-) ` reacts with it
` CH_3 COO^(-) +H^(+) to CH_3 COOH`
