The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
Q. Explain about Thiosulphuric Acid? Thiosulphuric acid, H 2 S 2 0 3 , has never been isolated but its salts are well known which contain the thiosulphate ion, S 2 O 2- 3 . Th
