A-level chemistry - Oxidation state, redox and half-equations - exam question walk through

Описание: Oxidation state is a tool that allows chemists to keep track of where electrons are!!! Assuming all bonds are ionic (they aren't), how many, if any, electrons would each atom lose or gain? Electron transfer occurs in redox process. A redox reaction includes both reduction and oxidation. When a species is oxidised it loses electrons,. When a species is reduced it gains electrons. Confused? Wait 'til you watch the video.
