Question

Why KCL appears to be violet sometimes instead of pure white ?

Answer 1

When a crystal of KCl is heated in an atmosphere of potassium vapour, the K atoms lose electron to form K+ions. The released electrons diffuse into the crystal and occupy anionic sites (F-centres). These electrons impart violet colour to the KCl crystal.
