If the crystals of a pure organic compound do not appear even after cooling the hot solution after a long time, then it may be necessary to scratch the sides of the dish with glass rod or to treat the hot solution with a small crystal of the same susbstance. This provides tiny fragments of gl,ass or small particles of the inducing crystallization. This process of inducing cyrstallization by adding a crystal of the pure substance into its saturated solution is called

A

feeding

B

seeding

C

impfing

D

both (2) and (3)

Text Solution

Verified by Experts

The correct Answer is:
D
Seeding or impfing is the addition of fine particles to a solution to induce crystallization. Each particle (often a tiny crystal of the solute) acts as a nucleus upon which the new crystal grows.
