Question 3
An oxidation number describes the combining capability of one ion to another ion or of one atom to another atom. Which of the following statements regarding oxidation numbers is FALSE?
H2S contains sulfur which has an oxidation number of -2.
Each oxygen in KMnO4 has an oxidation number of -2, and the oxidation number of K is +1; therefore, the oxidation number on Mn in this compound is +7.
The oxidation number of a monoatomic ion is the same as its ionic charge, such that Na ion has an oxidation number of +1.
The oxidation number of each atom in an element is zero, such that the oxidation number of Cl2 is -2.
Question 4
