How about giving us a little context? Is this a school assignment? If so, what level? That so we know how much detail to go into. If it's for school, how much work have you done already? Show us.
If this is more of a citizen chemist sort of interest, then ask us the whole question you have. If you have some info already, let us know, so we know what sense you mean it, and what discipline you're starting from.
