The ionization constant of propanoic aci...

The ionization constant of propanoic acid is `1.32xx10^(-5)`. Calculate the degree of ionization of the acid in its `0.05 M` solution and also its `pH`. What will be its degree of ionization if the solution is `0.01 M` on `HCl` also?

Text Solution

Verified by Experts

The correct Answer is:
`alpha=1.62xx10^(-2)` , pH=3.09 , `alpha` (in the presence of HCl)=`1.32xx10^(-3)`
