Ionic liquids (ILs) containing small amounts of water are called hydrated ILs and they show diverse physico-chemical properties that are strongly dependent on their water content. Some properties of hydrated ILs, such as biological activity and phase transition behaviour, were found to change non-linearly, with an inflection at a water molecule to ion pair ratio of around 7:1. This critical hydration number of ILs has been discussed in this paper with respect to the state of solvated water molecules.
含有少量水的离子液体（ILs）被称为水合离子液体，它们表现出多样的物理化学性质，这些性质强烈依赖于其含水量。人们发现，水合离子液体的一些性质，如生物活性和相变行为，会呈非线性变化，在水分子与离子对的比例约为7:1时出现拐点。本文已就溶剂化水分子的状态对离子液体的这一临界水合数进行了讨论。
