摘要：By considering a first-order variation in electroaccepting and electrodonating powers,omega(+/-), induced by a change from gas to aqueous solution phase, the solvent effect on omega(+/-) for charged ions is examined. The expression of electroaccepting and electrodonating powers in the solution phase, omega(+/-)(s), is obtained through establishing the quantitative relationship between the change of the omega(+/-) due to the solvation and the hydration free energy. It is shown that cations are poorer electron acceptors and anions are poorer electron donors in solution compared to those in gas phase. We have proven that the scaled aqueous electroaccepting power, omega(+/-)(s), of cations can act as a good descriptor of the reduction reaction, which is expected to be applied in the design of solution reactions.
