Solution: What is the oxidation number of Cl in perchloric acida. +7b. +5c. +1d. -1e. -5


What is the oxidation number of Cl in perchloric acid

a. +7

b. +5

c. +1

d. -1

e. -5


Determine the molecular formula of perchloric acid and calculate for the oxidation number of Cl using the rules for oxidation states

Rules for Naming Oxyacids:

a. If the polyatomic ion ends with -ate then change the ending to -ic acid

b. if the polyatomic ion ends with -ite then change the ending to -ous acid

  • If we have perchloric acid, it must have come from perchlorate ion
