Calculate the pH of 0.125M of H(2)SO(4)....

Calculate the pH of 0.125M of `H_(2)SO_(4)`.

Text Solution

Verified by Experts

`H_(2)SO_(4)to2H^(+)+SO_(4)^(2-)`
`[H^(+)]=2[H_(2)SO_(4)]=2xx0.125=0.25`
`pH=-log_(10)[H^(+)]=-log_(10)[0.25]=-log_(10)[2.5xx10^(-1)]`
`pH=-log2.5-log10^(-1)=-0.3979+1=0.6021`.
