REDOX REACTION

2. A redox reaction is a chemical reaction that involves reduction and oxidation that occurs simultaneously.
5. an atom is said to be reduced when its oxidation state
10. compound that is oxidised is the reducing agent.
11. In a reaction of displacement of metal, a metal which is placed on the top of the electrochemical series is more electropositive
12. an atom is said to be oxidised when its oxidation state
13. is the process of losing oxygen.
14. is the process of gaining oxygen.
16. Oxidation occurs when a reactant loses electron.

1. The electrochemical series is a series of arrangement of metals according to the order of the tendency of the metal to lose electrons to form positive ions.
3. in a redox reaction, a compound that is reduced is the oxidizing agent.
4. reaction is one in which a single substance is both oxidised and reduced.
6. The metal which is more electropositive corrodes and acts as the anode.
7. The more electropositive metal acts as a reducing agent. The metal experiences oxidation and is oxidised to a metal ion.
8. The less electropositive acts as the cathode and is protected from corroding. This method is known as the cathode protection or electrochemical protection.
9. Reduction occurs when a reactant gain of electron.The gain metal ions are weak oxidising agents because they do not have a tendency to gain electrons.
15. there is a transfer of electrons from a more electropositive metal to the ions of a metal which is less electropositive
