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))`

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

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

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

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

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

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

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

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

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

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