• A. Oil in water
• B. Cornflakes in milk
• C. Salt in water
• D. Sugar in milk

Answer 1

The correct option is B

Cornflakes in milk

The explanation for the correct answer

(B) Cornflakes in milk

Filtration

• Filtration is a separating technique that is used to separate solid matter from liquid.
• Filtration is done by passing the mixture through a pores membrane called a filter.
• There are different types of separating techniques for different types of mixtures.
• Here, Cornflakes in milk, are a solid-liquid mixture.
• Cornflakes are insoluble in milk. Hence, It can be separated easily by filtration.

Hence, Option (B) Cornflakes in milk is correct.

The explanation for the incorrect answer

(A) Oil in water

• It is a liquid-liquid mixture.
• They are immiscible liquids. It cannot be separated by the filtration process.
• It can be separated by using a Separating funnel.

(C) Salt in water

• It is a Solid-liquid mixture.
• Salt is soluble in water. It cannot be separated by the filtration process.
• Salt can be separated from water by evaporation.

(D) Sugar in water

• It is a Solid-liquid mixture.
• Sugar is soluble in water. It cannot be separated by the filtration process.
• Sugar can be separated from water by distillation.

Therefore, Option (B) Cornflakes in Milk is correct.
