The pH of the mixture of 25 ml of 0.01 M of `CH_3 COOH (K_a of CH_3 COOH = 5 xx 10 ^(-5) ) and 25 ml of 0.01 M` of NaOH solution is

A

`7`

B

` 8`

C

` 10. 25`

D

` 9. 125`

Text Solution

Verified by Experts

The correct Answer is:
B
complete neutralization
` pH =7 + ((pK_a+log c)/( 2)) `
` = 7+ (( 5- log 5 + log ""(0.01)/(2))/( 2)) =7+ ((5-3)/(2))=8`
