acidified potassium manganate (VII)
IDENTIFY
WHICH ONE IS OXIDISING AND
REDUCING AGENT
potassium iodide
acidified potassium manganate (VII)
HO
W?
• Note down the colour of the reagent.
• Observe the colour change during the
r e a c t i o n . ( Yo u t u b e V i d e o )
• Write down balanced chemical equation.
• Identify if the reagent is reducing agent or
oxidising agent.
• Present with evidence.
