Estimate the degree of dissociation of a 0.200 m solution of nitrous acid (Ka=4*10-4) that is also 0.500 m in the strong electrolyte BaCl2. Calculate the degree of dissociation for the HNO2 in pure water and in the BaCl2 solution. Use the Debye-Huckel limiting law for the mean activity coefficient for hydrogen ion and nitrite ion. Compare your results with the degree of dissociation of the acid in the absence of other electrolytes.

mean activity coefficient of nitrous acid=0.754

mean activity coefficient of BaCl2=0.397
