A little help with my chemistry

[wyz135]

I have a little difficulty in handling this chapter: Acid, Bases and Salts. How do I actually tell whether a salt is soluble or insouble? Like by looking at their chemical formula. Example: Sodium Chloride, Calcium Sulphate, Copper(II) Sulphate and Ammonium Phosphate are examples of soluble salts. Lead(II) Nitrate (can't think of anymore) are examples of insoluble salts.

Anyway thanks:)

Thanks for that chart:) All I need to know now is that all Alkali and Ammonium salts are soluble, all salts of Sulphate except Lead, Barium and Stromtium are soluble, all nitrade salts are soluble..... once again thanks:):):)

I'd like some potassium nitrate... would be fun to play with :P .

lol.... I would like some potassium chlorate:)

[Radiator]

Potassium nitrate tends to blow up rather easily , potassium chloride is as unstable as sodium chloride .
Edit :Oops my bad , I read Potassium Chloride at first ... that's what I get from reading stuff when not completely sober or awake .

I just want some pure white potassium. And I'll take it out of the water and throw it at people I don't like.

I would just eat it ... speaking of eating , I'm hungry .

Another question which is bothering me: Is it true oxide/carbonates of unreactive metal (copper, silver, gold etc. which will not react with acid in pure form) will react with acid to form the salt of the unreactive metal??
