Question

Why the oxidation state of zinc is +2

Answer 1

Answer:

the oxidation number of zinc (Zn) as an uncombined atom is 0, and the oxidation number of hydrogen in H2 is 0. The oxidation number of a monatomic ion is the charge on that ion. In ZnCl2, the oxidation number of chlorine as Cl- is -1 and that of zinc as Zn2+ is +2.
