Q 1119123910.     A buffer solution contains `500 `ml of `0.2 M CH_3COONa and 500 `ml of `0.1` M `CH_3COOH. 1 L` of water is added to this buffer.

What will be the pH before and after dilution? `(pK_a` of `CH_3COOH = 4.74)`

A

`5.04, 5.04`

B

`5.04, 4.89`

C

`4.89, 5.04`

D

`5.04, 3.74 `

HINT

Use formula: `pH ``= pK_a + log([[CH_3COO^−]]/[[CH_3COOH]])`
