Please help! I need to know how you can use the periodic table to make predictions of the soluabilities of compounds of groups1 and 2 ... and also 16 adn 17. mainly magnesium carbonate, sodium carbonate, potassium carbonate, and calcium carbonate... and also copper (II) oxide, copper (II) chloride, copper (II) bromide, and copper (II) sulfide. PLEASE HELP!

i dont know how to do it, but it depends on the solvent.

solvent as in what its being mixed with? because if thats it.. its just being mixed with water thanks for the reply either way/

i belive you would figure it out by seeing what kind of bonding it has, how strong. Something like that.

MgCO3 shouldnt be particualrly soluble, as carbonates tend to not be very soluble. Na2CO3 should be soluble just because of the Na+. same goes for K2CO3. CaCO3 should be mostly insol because it's a group 2 carbonate. cupric oxide should form the insoluble hydroxide. cupric chloride and bromide should be slightly soluble. cupric sulfide shouldnt be soluble.

but budellewargh can u use the periodic table to find that?

it's second nature. i can predict the properties of just about anything, save a few macromolecules, namely proteins and the like that are receptor specific. hard to explain.
