Comparing it with the standard electrode potential of nitric acid,the reason of dissolution of HgS in aqua regia was quantitatively revealed,and this is that the high concentration of chloride ions reduces the reduction potential of sulfur in HgS,thus raising the reducing power of HgS rather than that the oxidizing power.

根据热力学平衡原理和设计的可逆电池反应，由 E~0Hg~(2++S/HgS数据，计算了 E~0HgCl_4~(2++S/HgS+4Cl~-数值，将其与 HNO_3的标准电极电位比较，定量地揭示了 HgS 溶于王水的原因在于该溶液中高浓度 Cl~-离子降低了 HgS 中硫的还原电位，从而提高了 HgS 的还原性所致，并非王水的氧化性比 HNO_3的更强。
