Question

Why does presence of excess of lithium makes LiCl crystals pink!?

Solution

When LiCl crystal is heated in presence of Li, the chloride ions move to the surface of the metal and combine with Li.
Li + Cl^- ------> LiCl + e^-.
The electrons produces diffuse into the crystal and occupy the holes (anion vacancies) produced by the missing halide ions.
