F.5.question--點知邊d鹽可溶於水,邊d吳溶

Nitrate:
all are soluble

Halide(chloride, bromide and iodide) :
all are soluble except
- silver halides
- lead(II) halides

sulphate:
all are soluble except
- calcium sulphate
- lead(II) sulphate
- barium sulphate

hydrogencarbonate:
all are soluble

carbonate:
all are insoluble except
- lithium carbonate
- sodium carbonate
- potassium carbonate
- ammonium carbonate

oxide:
all are insoluble except
- calcium oxide
- sodium oxide
- potassium oxide

hydroxide:
all are insoluble except
- calcium hydroxide (slightly)
- sodium hydroxide
- potassium hydroxide

well.......if Sodium, Potassium and ammonium ion,and metal nitrate , all are soluble
if cholride.....all are soluble, except silver and lead chloride
if sulphate......all are soluble, except calcium, lead and barium sulphate
if carbonate and sulphite..all are insoluble, except Sodium, Potassium and ammonium ion
if hydroxide, all are insoluble, except Sodium, Potassium (there is no Ammonium hydroxide)

soluble: all nitrate, hydrogencarbonate, sodium, potassium, ammonium salts
all silver(I), and lead(II) halide(F, Cl, Br, I) is insoluble but redissolves in conc. hydrogen halide
all sulphate except those of Ba2+ and Pb2+
insoluble: all sulphide of non-group I metal ion
carbonate of Li+ and other non-group I metal ion

Very easy, all metal nitrates and chloride are soluble in water :)
