Potassium chlorate, or potassium perchlorate?
-
Von, don't depend upon memorization or tables for this type of question.
What's the oxidation state of Cl in the chlorate anion? Using the periodic table, it's important you deduce that it's +5.
What's the oxidation state of Cl in the perchlorate anion? You'll find that it's +7.
Now, you have two oxidizers, Cl(5+) and Cl(7+). Keep in mind that an oxidizer is something that readily accepts electrons.
Which would you expect to more readily accept electrons? Cl(5+) or Cl(7+)? Which one is more positive? Would you expect the most positive to be most receptive toward receiving electrons? What does this mean in terms of oxidation strength?
