Name the oxidising agent and the reducing agent in each.
Need a reminder? The key ideaShow
Oxidation is a gain of oxygen or a loss of hydrogen; reduction is a loss of oxygen or a gain of hydrogen. They happen together. The oxidising agent gives oxygen (or takes hydrogen) and is itself reduced; the reducing agent takes oxygen (or gives hydrogen) and is itself oxidised.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) gives its oxygen to carbon: it is the oxidising agent. Carbon takes the oxygen: it is the reducing agent.
Step 2. (b) loses its hydrogen, so it is oxidised: it is the reducing agent. loses its oxygen, so it is reduced: it is the oxidising agent.
Answer: (a) and C. (b) and .
