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.
wht is the difference between molar mass & molecular mass?
Write the periods of periodic table have d-block element
Q. Sometimes (surprisingly!) it is easier to do mass transfer measurements than heat transfer ones. As part of a study you have been asked to determine the heat transfer coefficien
