`4g` of `NaOH` was dissolved in one litre of a solution containing one mole of acetic acid and one mole of sodium acetete. Find the pH of the resulting solution (`K_(a)` of acetic acid is `1.8xx10^(-3)`)A. `4.70`B. `4.83`C. `5.92`D. `6.87`

Answer» Correct Answer - B
`pH=pKa+log["Salt"]/[["Acid"]]=4.74+log[1.1]/[[0.9]]`
Reaction :
`CH_(3)COOH+NaOHrarrCH_(3)COOHNa`
`{:(1," ",0.1," ",1),(1-0.1," ",0," ",1.1):}`
