常见可溶性盐与不可溶性盐


1、常见的可溶性盐有钠、钾和铵等阳离子和酸根离子组成的盐,如碳酸钾、硝酸铵、硫酸钠、氯化铵等盐;

2、常见的不溶性盐有硫酸钡、氯化银、溴化钡、碳酸钙、氢氧化镁、氢氧化钡、碳酸钡、碳酸镁。

盐的溶解性表的口诀:

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;

强酸:硫酸,盐酸,硝酸,氢溴酸,氢碘酸,高氯酸

中强酸:磷酸,亚硫酸,(底下有位说HF的,氢氟酸是弱酸)

强碱:氢氧化钠,氢氧化钾,氢氧化钡,氢氧化钙溶液(单说氢氧化钙是错的,因为只有溶于水的氢氧化钙才呈强碱性,氢氧化钙微溶于水)

可溶性盐:只能举例说明,太多了,(硝酸根的盐都可溶),NaCl,FeSO4,CuSO4,MgSO4

(碳酸根的仅有Na,K,铵根等可溶)

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(NO

Soluble Salts

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。
