The molar conductivity of acetic at infi...

The molar conductivity of acetic at infinite dilution is `390.7` and for `0.01 M` acetic acid is `3.9.7 S cm^(2)mol^(-1).` Calculate `(a) alpha ` and `(b) pH` of solution.

Text Solution

Verified by Experts

`alpha=(wedge_(m)^(c))/(wedge_(m)^(@))=(3.907).(390.7)=0.01`

`:.[H^(o+)]=calpha=0.01xx0.01=10^(-4)M`
`pH=-log (10^(-4))=4`
