The ionization constant (K(a)) of a weak...

The ionization constant `(K_(a))` of a weak electrolyte is `2.5xx10^(-7)`, while `wedge_(eq)` of its `0.01M` solution is `19.65S cm^(2) eq^(-1)wedge^(@)._(eq)` is `……………….` .

Text Solution

Verified by Experts

The correct Answer is:
`(392 S cm^(2) eq^(-1))`
`(392 S cm^(2) eq^(-1))`
`K_(a) = c alpha^(2)`
`2.5xx 10^(-7)=10^(-2)xxalpha^(2)impliesalpha=5xx10^(-2)`
`alpha=(wedge^(c)._(eq))/(wedge^(@)._(eq))`
`=5xx10^(-2)=(19.65)/(wedge^(@)._(eq))implieswedge_(eq)^(@)=392 S cm^(2)eq^(-1)`
