Immiscibles /Liquid-liquid mixtures

To form water-turpentine oil and Kerosene-water miscibles

Procedure

(i)Measure 50cm3 of water into 100cm3 beaker. Measure 50cm3 of turpentine oil. Place the oil into the beaker containing water. Swirl for about one minute.

(ii) Measure 50cm3 of water into 100cm3 beaker. Measure 50cm3 of kerosene. Place the kerosene into the beaker containing water. Swirl for about one minute.

Observation

Two liquids form layers.

Turpentine and water do not form a uniform mixture.

Water and kerosene do not form uniform mixture

Explanation

Kerosene is immiscible in Water.

Water is immiscible in turpentine oil. Immiscible mixtures do not form uniform mixtures.

They form layers. The size of the particles of one liquid is almost equal to the particles of the other.

The particles of one liquid cannot occupy the spaces between the particles of the other.

The heavier particles settle at the bottom. The less dense particles settle on top.
