The Hydrous Gibbs Free-energy and Hydrous Entropy Change of NTO Anion and the Enthalpy Change of Hydrous Process of System [M~(n+)(g)+nNTO~-(g)+mH_2O(g)]

A simple formula of estimating the standard hydrous Gibbs free-energy of NTO anion ΔhGθm(NTO-,g) was presented.The values of ΔhGθm(NTO-,g) of-267.24kJ·mol-1 and ΔhSθm(NTO-,g) of 380.71 J·(K·mol)-1 were obtained by the established formula and thermodynamic relation.The enthalpy changes of hydrous processes for systems [Mn+(g)+nNTO-(g)+mH2O(g)](M=La,Ce,Pr,Eu,Sm,Gd,n=3,m=7;M=Y,Yb,n=3,m=6;M=Dy,Tb,n=3,m=5;M=Nd,n=3,m=8) were obtained by a tehrmochemical cycle.
