    What questions do you have? I will try to help. I find Chemistry is like Math. Practice, practice, practice the sample equations. Memorize the theories and formulas. Sorry I don't know of any specific sites on the internet.

    Well, I don't really understand conjugate acid/base pairs. I can point them out in an equation but I can't tell you what they are.
