The experimental results show that, when the water is evaporated, the trace metal ions Zn2+ etc contained in this water can transfer in 100% concentration to water vapor under the limiting concentration of transfer. Therefore, the free energy, △Go, can not be used directly to predict the feasibility of this trace concentration physico-chemical process. Occurrence of the thermodynamics anomaly phenomenon in trace concentration physico-chemical system is presented experimentally in the present paper.
