Acetic acid has a dissociation constant ...

Acetic acid has a dissociation constant of `1.8xx10^(-5)`, Calculate the pH values of the decinormal solution of Acetic acid.

Text Solution

Verified by Experts

`[H^(+)]=sqrt(K_(a).C)" "C=0.1M`
`sqrt(1.8xx10^(-1)xx10^(-1))=1.34xx10^(-3)`
`pH=-log[H^(+)]=-log01.34xx10^(-1)=2.872`
