    What exactly are the differences between these suffixes? I saw a question on destroyer that expected you to know the difference between sulfide and sulfite so I'm guessing questions like these pop on the DAT too. THanks!

    This is the way I remember it:

    "Ate" and "Ite" have to do with oxygen compounds. The "Ate" has the higher value of Oxygens, and the "Ite" has the lesser value. I remember it as " I "ATE" to much O2!". Weird, but it helps. The "Ide" deals with monoatomic ions that are by themselves with their natural charge/oxidation numbers, such as Flouride, (-1), Sulfide (-2), etc.

    Also remember the name of your acids between -ous and -ic.

    by order of decreasing oxygens,

    hyper-ic > -ic > -ous >hypo-ous

    -ic acid deprotonates to an -ate ion
    -ous acid deprotonates to an -ite ion
    -ide is usually just denotes a moiety
