Question

where does the colour of kMno4 go when it comes it with mohr salt oxalic ​

Answer 1

Answer:

When you perform a redox titration with permanganate, the titrant (KMnO) in the burette is deep purple in colour. This is because the concentration is quite large. When you start the titration, the dark purple KMnO is slowly added into the sample you are titrating.
