How to name K2C204

  1. Oct 13, 2008 #1
    1. The problem statement, all variables and given/known data

    It is simply naming K2C204, but I can't seem to name it..

    2. Relevant equations

    None

    3. The attempt at a solution

    I'm thinking Potassium Perchlorate, but it isn't right, because then that would be K2C206..!

    C is carbon, so no way for chlorate or perchlorate to be right.

    What carbon containing acids do you know?

    ... None? I'm in Phys 11(Unfortunately Higher Level) and my teacher's just thrown this nomenclature at us...(ionic/covalent bonds)

    Should I know?!
    aaargh!

    No. This is a carboxylic acid. Google what that means.

    Stop guessing, check what they are.

    K(+) and C2O4(2-)
    That makes K2C2O4. C2O4 is oxalate. That means this compound is named Potassium oxalate...
