How can redox reactions be identified using acidified aqueous potassium manganate (VII)?
gpt
Redox reactions can be identified using acidified aqueous potassium manganate (VII) by looking for colour changes from purple to colourless.
Explanation: Acidified potassium manganate (VII) is an oxidizing agent that turns colourless when reduced, making it a useful indicator for identifying redox reactions.
