I am really confused with colour changes of "potassium manganate(v11)" . I know that it changes to colorless with acids and it is originally purple
But sometimes it changes to pink ,brown or colourless.
Can someone PLZ make it clear to me, & and I will be very thankful.
Manganese is oxidised to different states , these different oxidation numbers have different colours , manganese (II) is brown in colour
