Question

We have three liquids A, B, and C. When liquids A and B are put together in a container, they form a single layer and the difference between the boiling point of A and B is more than $25{}^{\circ }C$. On the other hand, when, liquids B and C are mixed, they form two separate layers. Which of below-mentioned separation technique is used to separate the mixture of A and B, B and C?

• A. Mixture A and B:- Separating funnel Mixture B and C:- Centrifugation
• B. Mixture A and B:- Distillation Mixture B and C:- Separating funnel
• C. Mixture A and B:- Fractional distillation Mixture B and C:- Separating funnel
• D. Mixture A and B:- Centrifugation Mixture B and C:- Separating funnel

Answer 1

The correct option is B

Mixture A and B:- Distillation

Mixture B and C:- Separating funnel

Distillation is a separation technique which is used to separate the components of a liquid-liquid mixture in which both the liquids are miscible with each other and the difference between their boiling points is more than $25{}^{\circ }C$.

Mixture A and B:- Distillation

Separating funnel is a separation technique which is used to separate the components of a liquid-liquid mixture in which both the liquids are immiscible with each other and forms distinct layers due to the difference in their density.

Mixture B and C:- Separating funnel
