Question

The components of which among the following mixtures can be separated by filtration?

• A. Ink in water
• B. Saltwater
• C. Cornflakes in milk
• D. Sugar in water

Answer 1

The correct option is C Cornflakes in milk

Filtration is a process of separation used when minute insoluble solids are present in a liquid. In this process a filter paper is used, which is a sieve with very minute holes.

* Salt is soluble in water, sugar is soluble in milk and ink mixes completely with water. Hence, the components of these mixtures cannot be separated by filtration.

* Cornflakes are insoluble in milk and hence, can be easily separated by filtration.
