Question

Impure crystalline (solid) substances can be purified by recrystallization from a suitable solvent. Arrange the steps of the recrystallization procedure, from start to finish.
Weigh the crystals into a tared flask.
Dissolve the crude substance in a minimum amount of hot solvent.
Filter the hot solution to remove the solid impurities (if present)
Allow the solution to cool slowly so crystals form.
Filter the crystals.
Dry the crystals

Answer 1

Answer:

1) Dissolve the crude substance in a minimum amount of hot solvent.

2) Filter the hot solution to remove the solid impurities (if present)

3) Allow the solution to cool slowly so crystals form.

4) Filter the crystals.

5) Dry the crystals

6) Weigh the crystals into a tared flask.

Explanation:

Recrystallization is a method used in chemistry to obtain crystals having a high degree of purity for the purpose of analytical or synthetic laboratory work.
