In a redox reaction, what happens to a species that is oxidised?
AIt gains electrons
BIt loses electrons
CIt loses protons
DIt gains protons
Answer & Solution
Correct answer: B. It loses electrons
1. Oxidation and reduction always happen together, because electrons have to go somewhere.
2. Oxidation is the loss of electrons by a molecule, atom or ion.
3. Reduction is the gain of electrons by a molecule, atom or ion.
4. The species that loses electrons hands them to another species, so it acts as the reducing agent.
