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.
Theory of conductomaetric titration NH4cl vs NaOH
The frequency corresponding to transition n= 2 to n =1 in hydrogen atom is: (1) 15.66 x 10 10 Hz (2) 24.66 x 10 14 Hz (3) 30.5
