a Given that Ka for HBrO is 28Solution a Kb KwKa 101428 x

(a.) Given that Ka for HBrO is 2.8

(a) Kb = Kw/Ka = 10^(-14)/2.8 x 10^(-9)

= 3.6 x 10^(-6)

(b) Ka = Kw/Kb = 10^(-14)/6.3 x 10^(-4)

= 1.6 x 10^(-11)

(a.) Given that Ka for HBrO is 2.8Solution (a) Kb = Kw/Ka = 10^(-14)/2.8 x 10^(-9) = 3.6 x 10^(-6) (b) Ka = Kw/Kb = 10^(-14)/6.3 x 10^(-4) = 1.6 x 10^(-11)
