State Ostwald's dilution law.

The degree of dissociation of weak electrolyde is inversely proportional to the square root fo concentration. It is called Ostwald's dilution law. alpha = sqrt((K_(a))/(c)) As the tempertaure increases, degree of dissociation will increase. (alpha_(1))/(alpha_(2)) = sqrt((K_(a_(1)))/(K_(a_(2)))) if concentration is same. (alpha_(1))/(alpha_(2)) = sqrt((c_(2))/(c_(1))) if acid is same. pH of 0.005 M HCOOH [K_(a) = 2 xx 10^(-4)] is equal to
