Question

What is a good oxidant?

Answer 1

An oxidizing agent is the element or compound in an oxidation-reduction (redox) reaction that accepts an electron from another species. Because the oxidizing agent is gaining electrons (and is thus often called an electron acceptor), it is said to have been reduced. Another term electron acceptor would be Lewis acid.

The oxidizing agent itself is reduced, as it is taking electrons onto itself, but the reactant is oxidized by having its electrons taken away by the oxidizing agent.

Answer 2

potassium chromate is a great oxidant.
