Answer for screen readers
The final answer is +7
More Information
In HClO4 (Perchloric acid), the oxidation number of chlorine is +7. This is determined by assigning oxidation numbers to hydrogen (+1) and oxygen (-2 for each of the four oxygens), and solving for chlorine to balance the overall charge of the molecule, which is neutral.
Tips
Ensure to correctly balance the total oxidation numbers of all atoms in the molecule to zero for neutral compounds.
