Which of the following statements about seed crystal are correct? Statement 1: Seed crystal provides a nucleation site. Statement 2: The recrystallization is done by seed crystal. Correct Answer True, True

Seed crystal provides a nucleation site on which crystals begin to grow. The recrystallization of the excess dissolved solute in a supersaturated solution can be originated by adding small crystal of solute is called a seed crystal.
