why ostwalds diluion law is applied to wrak electrolytes not strong

Answer 1

hello....

▶▶Ostwald's dilution law is only applicable to weak electrolytes and not strong electrolytes because in the case of strong electrolytes the dissociation is complete

▶▶nearly equal to one so cα will nearly be equal to zero

▶▶so Ka will tend towards infinity. But for dilute solutions α is fairly small and hence
c2α2/c(1-α) = cα2/1-α
can be used to calculate the dissociation......

thank you.....

Answer 2

>>Degree of dissociation of weak electrolyte is directly proportional to square root of dilution. This law is not applicable for strong electrolytes because strong electrolytes completely ionize at all dilution.<<
