I understand i need to talk about the polar nature of water but i don't quite understand what the rest of the question is asking. I also know i need to talk about ionic substances, polar covalent substances and other covalent substances which make hydrogen bonds with water but don't know what to write about them. I'm a bit confused.



Would appreciate some pointers to get me heading in the right direction.


Thanks.

 

[shady145]

heard of the term like dissolves like
eg polar substances dissolve in polar solvents
so all* maybe most ionic substances are polar and thus dissolve in water
mention why water is polar
whats the link between the solubility of substances and the polar nature of water

Thanks mate, much clearer now.
