How do you balance this redox reaction using the oxidation number method? KClO3(s) → KCl(s)+O2(g)
Assign oxidation states to each element in the equation. Tell us a little about yourself to get started. If you were already told it was a redox reaction, then your first step is to split it into two half-reactions. Periodic table About author. Post as a guest Name. If you can show it by half reaction method then also it will work, because i have test tomorrow.
