The temperature and concentration variations in 207Pb NMR shifts of Pb(NO3)2 in aqueous solutions are analyzed in terms of exchange between aquated lead ion and the Pb(NO3)+ ion complex according to the reaction PbNO3+(aq) = Pb2+(aq) + NO3-(aq). The analysis gives an enthalpy of dissociation of −3.0 ± 0.2 kcal mol-1 and an entropy of dissociation of −11.9 ± 0.4 cal K-1 mol-1.
