Question

Anhydrous crystals have no geometric shape reason

Answer 1

Answer:-

The geometric shape of single crystals arises from the molecular level order that the atoms arrange themselves in: the crystal structure. ... Many common crystals are in the cubic system, so many exhibit similar shapes when the molten mineral slowly solidifies into one crystal, with a defined shape.

i hope ! i have helped u.

Answer 2

Answer:

Water of crystallisation is what causes geometric shapes of crystals. Since crystals of anhydrous salts don't possess them, they have no geometric shape or colour.
