I mean if it ends in oxide/carbonate/hydroxide/if a an alkali metal is present??? I'm not sure

Sachacohen2 Posted at 3:49 pm on May 25, 2008 Quote: from WaterMolecules at 3:47 pm on May 25, 2008 My chemistry is a little rough, but it all comes down to polarity. If the molecule is polar, it will be soluble. You will need to remember which kinds of compounds are polar. The only one I can remember off the top of my head are oxides. They are definitely polar. what does polar mean? WaterMolecules Posted at 3:47 pm on May 25, 2008 My chemistry is a little rough, but it all comes down to polarity.
