Oxidising and reducing agents
Name strong oxidising agents
Hydrogen peroxide
Acidified permanganate
Acidified dichromate solutions
The oxidising property of hydrogen peroxide makes it useful as?
A bleaching agent, to remove colour from materials
The oxidising property of the permanganate ion makes it effective in?
Killing fungi and bacteria, and can also deactivate viruses
In what order does the electrochemical series list substances?
In order of how well they act as reducing/oxidising agents
Where are strong reducing agents found in the electrochemical series?
Top right
Where are strong oxidising agents found in the electrochemical series?
Bottom left
How are ion-electron equations written in the electrochemical series?
Written as reductions, but can be reversed to obtain the oxidation equation
