Which separation technique is used to separate kerosene oil water and salt?
Answers
Separating funnel is used to separate the mixture of two immiscible liquids. Kerosene oil and water do not mix with each other and form two separate layers. The mixture separates into two layers according to their densities.
Answer:
This is based on the concept of evaporation and separating funnel.
Explanation:
Kerosene oil, water and salt can be separated with two techniques separating funnel and evaporation.
First we will separate Kerosene oil and water and then separate salt from water.
As Kerosene oil and water are immiscible in solution, so separating funnel separate them out in layers depending on their densities. when Kerosene oil and water are pour into separating funnel, kerosene oil having less density comes at top while water with higher density settle at bottom and water is then removed from bottom.
Then, water and salt are miscible so the process of evaporation is used to evaporate water with a light source and it will left with layer of salt in the bottom.
Some other techniques can also used for separation of kerosene oil, water and salt such as distillation and crystallization.
