SCREW.CHEM.
i'm screwing everything man. hmph.

stupid colours. and dissolve in excess ______; insoluble in excess _____.
test for water. use the cobalt (II) chloride paper. it turns it from blue to pink :D

SODIUM CARBONATE, POTASSIUM CARBONATE, AMMONIUM CARBONATE ARE SOLUBLE. the rest of the carbonates. INSOLUBLE.

ALL NITRATES ARE SOLUBLE! :D

LEAD SULPHATE, BARIUM SULPHATE, CALCIUM SUPHATE- INSOLUBLE. the rest are. (:

ALL chlorides are soluble cept for lead chloride and silver chloride.

all oxides are insoluble except for sodium oxide, potassium oxide, ammonium oxide and calcium oxide.

all hydroxides are insoluble except for sodium hydroxide, potassium hydroxide, barium hydroxide and calcium hydroxide.

acidic oxides are oxides of nonmetals. and they react with water to produce acid. they react with alkaline to produce salts and water.

basic oxides are oxides of metals. they react with acids to produce salt s and water.

amphoteric oxides behave as an acidic oxide OR basic oxide. they react with acids and alkalines to form salts.

neutral oxides DONT have reaction at all lar. therefore, no salts. hah.

YOU SEE WHY I HATE CHEM SO MUCH? it doesnt make much sense at all. besides. i dont know. i havent seen anything that is common sense yet. and it's such a stupid subject. HMPH. I HATE CHEMISTRY! i think the whole world knows that. but still.
