The specific conductivity of dichloroacetic acid at dilution of 8 litres is 0.0238 C.G.S. unit, lambda_0fomthis acid is 385 C.G.S. unit, calculate the degree of jonisation at this dilution.

Answer»

`50%`
`45%`
`49.45%`
`36.02% `

Solution :`^^_M = K XX V(ML) = 0.0238 xx 8 xx 1000 = 190.4 , alpha = (^^_M)/(^^_M^(0)) = (190.4)/(385) xx 100 = 49.45%`
