What is reduction

Process of electron gain

What is an oxidising agent

Gains electrons as they themselves are reduced

What is a reducing agent

Lose electrons as they themselves are oxidised

What are the rules to balancing half equations

• write down species before and after the reaction

• Balance the atoms

• Balance the oxygen with water

• Balance the hydrogen with H+ ions

• Balance the charges with electrons

What is the affect of reduction on the oxidation number

The number decreases
