可溶性盐有哪些
1. The Na+, K+, and NH4+ ions form soluble salts. Thus, NaCl, KNO3, (NH4)2SO4, Na2S, and (NH4)2CO3 are soluble.
Na+、K+、NH4+盐溶
2. The nitrate (NO3-) ion forms soluble salts. Thus, Cu(NO3)2 and Fe(NO3)3 are soluble.
硝酸盐溶
3. The chloride (Cl-), bromide (Br-), and iodide (I-) ions generally form soluble salts. Exceptions to this rule include salts of the Pb2+, Hg22+, Ag+, and Cu+ ions. ZnCl2 is soluble, but CuBr is not.
除了Pb2+/Hg22+/Ag+/Cu+的盐不溶,卤素化合物溶.
4. The sulfate (SO42-) ion generally forms soluble salts. Exceptions include BaSO4, SrSO4, and PbSO4, which are insoluble, and Ag2SO4, CaSO4, and Hg2SO4, which are slightly soluble.
硫酸银、硫酸钙、硫酸亚汞微溶；硫酸钡、硫酸锶、硫酸铅不溶.别的都溶.
Insoluble Salts

1. Sulfides (S2-) are usually insoluble. Exceptions include Na2S, K2S, (NH4)2S, MgS, CaS, SrS, and BaS.
硫化物的溶解情况.Na2S, K2S, (NH4)2S, MgS, CaS, SrS, and BaS这些可溶.
2. Oxides (O2-) are usually insoluble. Exceptions include Na2O, K2O, SrO, and BaO, which are soluble, and CaO, which is slightly soluble.
氧化物基本上不溶.碱金属碱土金属氧化物溶于水发生反应.

3. Hydroxides (OH-) are usually insoluble. Exceptions include NaOH, KOH, Sr(OH)2, and Ba(OH)2, which are soluble, and Ca(OH)2, which is slightly soluble.
氢氧化物一般不溶,除了NaOH/KOH/LiOH、Sr(OH)2/Ba(OH)2可溶、Ca(OH)2微溶.
4. Chromates (CrO42-) are usually insoluble. Exceptions include Na2CrO4, K2CrO4, (NH4)2CrO4, and MgCrO4.
铬酸盐,可以溶的有：Na2CrO4, K2CrO4, (NH4)2CrO4, and MgCrO4.
5. Phosphates (PO43-) and carbonates (CO32-) are usually insoluble. Exceptions include salts of the Na+, K+, and NH4+ ions.
磷酸盐,可以溶的有：Na+,K+, NH4+ ,不溶的磷酸盐变为磷酸氢盐或者二氢盐会变成可溶.
还有口诀：盐的溶解性表
钾钠铵盐硝酸盐,放入水中都不见
硫盐酸盐多可溶,顽固沉淀要记清
碳磷酸盐多不溶,钾钠铵盐才可溶
可溶碱类用五类：钾钙钠铵钡!
注：硫盐酸盐多可溶 中的 硫盐酸盐 指的是硫酸盐和盐酸盐
顽固沉淀指的是：硫酸钡和氯化银
氢氧化钙当然是微溶

NaCO3,NaHCO3,NaCl,NH4Cl,NH4NO3，(NH4)2SO4，(NH4)2SO3，NaNO3，NaNO2,
KClO3, KCl,KNO3,K2SO4 ,CuSO4,CuCl2， AgNO3,BaCl2,BaNO3,CaCl2,Ca（NO3）2，Ca（HCO3）2，FeCl2,FeCl3,FeSO4,Fe（NO3）2,Fe(NO3)3,Fe2(SO4)3，KMnO4，实在不想写了
