1.	Given HF +H_2O overset( K_a) hArr H_3 O^(+)+F ^(-) , F^(-)+H_2O overset( K_a) hArr HF +OH^(-) Which relation is correct:
Answer» `K_axx K_b =K_W` ` K_b =1//K_W` ` K_a=K_b =K_W` ` K_a//K_b =K_W` SOLUTION :` HF +H_2O HARR H_(12) O ^(+)+F^(-),K_a` `(F^(-)+H_2OhArr HF +OH^(-),K_b )/(2H_2hArr H_3O ^(+) +OH^(-) ,K_W=K_a.K_b) `
