A buffer solution is prepared by mixing ...

A buffer solution is prepared by mixing `10ml` of `1.0 M` acetic acid & `20 ml` of `0.5 M` sodium acetate and then diluted to `100ml` with distilled water. If the `pK_(a)` of `CH_(3)COOH` is `4.76`. What is the pH of the buffer solution prepared?

Text Solution

Verified by Experts

The correct Answer is:
4.76

`pH=pK_(a)+log("[Salt]")/("[Acid]")=4.76+log((20xx0.5)/10)=4.76`
