The specific conductivity of dichloroacetic acid at dilution of 8 litres is 0.0238 C.G.S. unit, `lambda_0`fom this acid is 385 C.G.S. unit, calculate the degree of jonisation at this dilution.

A

`50%`

B

`45%`

C

`49.45%`

D

`36.02% `

Text Solution

Verified by Experts

The correct Answer is:
C
`^^_M = K xx V(ml) = 0.0238 xx 8 xx 1000 = 190.4 , alpha = (^^_M)/(^^_M^(0)) = (190.4)/(385) xx 100 = 49.45%`
