The value of pKb for the base ethylamine (CH3CH2NH2) is 3.19 at 25°C, while the pKa for formic acid
(HCO2H) is 3.74, also at 25°C.
a)
Calculate
the value of the equilibrium constant Kc for the following aqueous equilibrium:
HCO2– (aq) + CH3CH2NH3+(aq)-->HCO2H(aq) + CH3CH2NH2(aq)

Check me out on this but I believe K for the hydrolysis of the salt is K = (Kw/KaKb)
Right. For the hydrolysis reaction K = Kw/KaKb.
For the acid + base ==> salt, K = KaKb/Kw
For the acid + base ==> salt, K = KaKb/Kw
