Interpretation:
The oxidation states of all the atoms in CrCl3 should be determined.
Concept Introduction:
The oxidation state is defined as the charge(s) that an atom would have when electron(s) were transferred completely from a molecule or ion.
Interpretation:
The oxidation states of all the atoms in K2 CrO4 should be determined.
