Question

what happens after five minutes when a potassium magnate(VII) crystal is placed in a beaker with cold water?

Answer 1

Answer:

Potassium Permanganate (KMnO4)

When it is added to water containing taste–odor compounds, the reaction is: 2 KMnO 4 + H 2 O + taste - and - odor compound → 2 MnO 2 ↓ + 2 KOH + 3 O − 2 + taste - and - odor compounds .
