as a rule of thumb, ionic compounds are water soluble. It gets more complicated, but if you are doing high school chem, check to see if it is an ionic or covalent compound. If it is ionic, it is water soluable.

Water Soluble Compounds

if it is NOT a organic compund :
1) if its ionic , then naturally its soluble in water cuz ionic compound dissociate almost completely in water.
if its not ionic dat is it is covalent , then its not soluble in water , cuz they dnt dissociate in water ( dissociation is relative).
[ if u r confused which one is ionic and which one covalent den u can think dat all metals will (mostly) form ionic and non-metals will form covalent ]
if it is organic compound:
1) polar organic compounds , which are capable of forming hydrogen are alwayz alwayz soluble in water cuz they from hydrogen bonds with d oxygen in water molecule ( wich is partially -ve) . to find polar compounds u can look for carboxyl group or hydroxy group or somehting lke dat in a organic compound cuz then they will b polar .
and as the hydro-phobic part of a organic compound increases it becomes less soluble in water.
2) non-polar organic compounds are simply not soluble in water.

thats not an easy task but here we can say all nitrate compounds are soluble.. some chlorides as barium ,,silver are not soluble,, some carbonates as calcium baruim ,,strontium not soluble,, all of bicarbonate are soluble,, some of phosphates as calcium hexaphosphate insoluble

1)Lead nitrate..PbNO3...ALL nitrates are water soluble. 2) Lead chloride PbCl2 Hey...I'm doing you homework for you...finish it yourself.

1. can it form hydrogen bonds
2. does it resemble things you know are water soluble
3. try it
