How does the degree of ionization (assuming lt lt 1)` of a weak electroyte vary with concentration ? Give exact relationship.

Verified by Experts

`alpha=sqrt(K_(i)//C)`. It is called Ostwald's dilution law (`K_(i)` is ionization constant and C is molar concentration of the eletrolyte).

If alpha is the degree of ionization, C the concentration of a weak electrolyte and K_(a) the acid ionization constant , then the correct relationship between alpha and C is

`alpha^(2) = sqrt(K_(a)/C)`

`alpha^(2) = sqrt(C/K_(a))`

`alpha= sqrt(K_(a)/C)`

`alpha = sqrt(C/K_(a))`

`alpha^(2) = sqrt((K_(a))/(C))`

`alpha^(2) = sqrt((C)/(K_(a))`

`alpha = sqrt((K_(a))/(C))`

`alpha = sqrt((C)/(K_(a))`

`a^2=sqrt((K_a)/C)`

`a^2=sqrt((C)/(K_a))`

`alpha = sqrt((C)/(K_a))`

`alpha = sqrt ((K_a)/(C))`
