### ZIMSEC O Level Combined Science Notes: Differences between reduction and oxidation

• There are differences between oxidation and reduction
• The table below shows the differences between oxidation and reduction:
 Oxidation Reduction There is addition of oxygen There is removal of oxygen There is removal of hydrogen There is addition of hydrogen Oxidising agent Reducing agent It adds oxygen It removes oxygen It removes hydrogen It adds hydrogen
• Often reduction and oxidation occur in conjunction
• That is at the same time and during the same reaction
• For example:
• $\text{ammonia+oxygen}\rightarrow\text{water+nitrogen dioxide}$
• Nitrogen gains oxygen and losses hydrogen (this is the oxidation part of the equation)
• Oxygen gains hydrogen (the reduction part of the equation)
