2. HOW CAN WE OBTAIN PURE
COPPER SULPHATE FROM AN
IMPURE SAMPLE?
 PROCESS INVOLVED: CRYSTALLISATION
WHAT IS CRYSTALLISATION?
CRYSTALLIZATION IS A TECHNIQUE USED
FOR THE PURIFICATION OF SUBSTANCES.
IT IS A SEPARATION TECHNIQUE TO
SEPARATE SOLIDS FROM A SOLUTION.
CRYSTALLISATION CAN BE DEFINED AS
SOLIDIFICATION OF A LIQUID
SUBSTANCE INTO HIGHLY STRUCTURED
SOLID WHOSE ATOMS OR MOLECULE ARE
PLACED IN WELL DEFINED 3-D CRYSTAL
LATTICE.

3. PROCEDURE
1. TAKE 5g OF IMPURE SAMPLE OF COPPER
SULPHTE IN A CHINA DISH.
2. DISSOLVE IT IN MINIMUM AMOUNT OF
WATER.
3. FILTER THE IPURITIES.
4. EVAPORATE WATER FROM COPPER
SULPHATE TO GET SATURATED SOLUTION.
5. COVER SOLUTION WITH FILTER PAPER AND
LEAVE IT UNDISTURBED FOR AT ROOM
TEMPERATURE TO COOL SLOWLY FOR A
DAY.
6. CRYSTALS OF COPPER SULPHATE ARE
OBTAINED IN CHINA DISH.

4. APPLICATIONS
1. PURIFICATION OF SEA WATER.
2. SEPARATIONOF ALUM CRYSTALS FROM
IMPURE SAMPLES.
3. IN PHARMACEUTICAL INDUSTRY ,
CRYSTALLIZATION IS USED AS A
SEPARATION AND PURIFICATION PROCESS
FOR THE SYNTHESIS AND ISOLATION OF
CO-CRYSTALS, PURE ACTIVE
PHARMACEUTICAL INGREDIENTS (API),
CONTROLLED RELEASE PULMONARY DRUG
DELIVERY AND SEPRATION OF ISO CHIRAL
ISOMERS.
