प्रश्न
The degree of ionization of a 0.1M bromoacetic acid solution is 0.132. Calculate the pH of the solution and the pKa of bromoacetic acid.

उत्तर
Degree of ionization, α = 0.132
Concentration, c = 0.1 M
Thus, the concentration of H3O+ = c.α
= 0.1 × 0.132
= 0.0132
`"pH" = - log["H"^+]`
`=- log(0.0132)`
= 1.879 : 1.88
Now
`"K"_"a" = "C" alpha^2`
`= 0.1 xx (0.132)^2`
`"K"_"a" = .0017`
`"pK"_"a" = 2.75`
