气体在水中的溶解是气体的一个重要性质 ,其溶解过程体现着各种各样的情况。如ＨＣｌ,ＨＢｒ,ＨＩ,ＮＨ3这一些气体易溶于水 ,标准状况下ＮＨ3在水中的溶解 ,按照体积比是 1∶70 0 ;有的易溶的 ,如标准状况下ＳＯ2 在水中的溶解 ,按照体积比是 1∶40 ;Ｃｌ2 是 1∶2 ,ＣＯ2 是 The dissolution of gas in water is an important property of gas, and its dissolution process embodies a variety of situations. Some gases such as HCl, HBr, HI and NH3 are easily soluble in water. Under normal conditions, NH3 is dissolved in water at a volume ratio of 1:70 0; some easily soluble, such as SO2 dissolved in water under standard conditions, According to the volume ratio is 1:40; Cl2 is 1: 2, CO2 is
