Colour of transition metal ions | the d-block elements | Chemistry | Khan Academy

In this video, we will explore the reasons behind why transition metal ions give a large number of coloured solutions in contrast to the s and p block elements that are predominantly white in colour. We will also look at the exceptions where certain metal ions form only white coloured compounds.

We'll explained, thankyou

2:10 the formula on the left shows copper sulfate pentahydrate, but on the right it shows a complex ion with water. Are water of crystallisation and water ligands not two separate phenomena?

Why can't i find the next topic??

[@venkatbadhrinarayanan2282]

next topic ?????

[@user-xz6ml6ng7f]

what the meaning visible region???

[@aastha7605]

energy of the photons absorbed are similar to the energy in visible region in the wave spectrum
