TO SEPARATE PURE WATER FROM COLOURED WATER BY DISTILLATION

MATERIAL REQUIRED

Distillation apparatus, Coloured Water, Bunsen Burner, Tripod Stand , Stand with clamps

THEORY

Distillation is a process that relies on evaporation to purify water. Mixture of water or impure water is heated to form steam. Inorganic compounds and large non volatile organic molecules do not evaporate with the water and are left behind. The steam then cools and condenses to form purified water. The ink is non volatile particle which can not evaporated during boiling of water. So pure water can be obtained from ink water by distillation.

PROCEDURE

• Take ink water in round bottom flask.
• Then round bottom flask connect with one end of condenser.
• Another end of condenser connect with collector flask.
• Heat flask to boil mixture.
• After steam generation, change water in condenser.
• The condensed pure water is collected in collector flak.

OBSERVATION

Water is escaped in the form of vapor from ink mixture and pure collected in collector after condensing in condenser.

RESULT

Pure water is separated from ink solution by distillation.

CONCLUSION

Hence pure water can be separated from ink water by distillation in laboratory.

PRECAUTION

Apparatus should be air tight.

Water should be frequently change in condenser or it should be connected to continue running tap water.

Flask should be heated gently.
