Question

why potassium permanganate act as self indicator​

Answer 1

Answer:

Hol@ mate!! Here is ur ans:-

Hope it helps!! Plzz mark me as brainliest.. $#^_^

Answer 2

Answer:

Here, KMno4 is potassium permanganate

Explanation:

KMno4 oxidises these standard solutions... This pale pink colour is due to the presence of very little amount of extra KMno4 is there is no more standard solution left to oxidises it. This KMno4 indicates that the standard solution was completely oxidized.Thus KMno4 acts as self indicator!!
