From the equilibrium concentrations given, calculate Ka for each of the weak acids and Kb for each of the weak bases.

(a)


HCH3CO2: [H3O+ ] = 1.76 ✕ 10−3 M, [CH3CO2 ] = 1.76 ✕ 10−3 M, [HCH3CO2] = 0.183 M

(b)


ClO: [OH ] = 2.41 ✕ 10−4 M, [HClO] = 2.41 ✕ 10−4 M, [ClO ] = 0.230 M

(c)


HC2H5CO2: [HC2H5CO2] = 0.388 M, [H3O+ ] = 2.25 ✕ 10−3 M, [C2H5CO2 ] = 2.25 ✕ 10−3 M

(d)


C6H5NH3+: [C6H5NH3+ ] = 0.253 M, [C6H5NH2] = 1.85 ✕ 10−3 M, [H3O+ ] = 1.85 ✕ 10−3 M
