　　溶解性：易溶于水。化學(xué)方程式為：(NH4)2S2O8+2H2O=（可逆）=2NH4HSO4+H2O2離子方程式：(NH4)2S2O8=2NH4++ S2O82- ，S2O82-+ 2H2O=(可逆)=2HSO4-+ H2O2，HSO4-=(可逆)=H+ + SO42-（所以過硫酸銨溶液中除了大量的銨根離子和過二硫酸根離子外，還存在少量的硫酸氫根離子和硫酸根離子，溶液水解顯酸性，加入硝酸可以抑制反應(yīng)正向進行）

　　Solubility: Easily soluble in water. The chemical equation is: (NH4) 2S2O8+2H2O=(reversible)=2N4HSO4+H2O2. The ion equation is: (NH4) 2S2O8=2NH4++S2O82-, S2O82-+2H2O=(reversible)=2HSO4-+H2O2, HSO4-=(reversible)=H++SO42-. Therefore, in addition to a large number of ammonium ions and persulfate ions, there are also small amounts of hydrogen sulfate ions and sulfate ions in the ammonium persulfate solution. The solution hydrolyzes and becomes acidic, and adding nitric acid can inhibit the forward reaction
