Question

Consider the table below:
$$\begin{array}{ccc}\text{Mixture}& \text{Component 1}& \text{Component 2}\\ \text{X}& \text{Chalk Powder}& \text{Water}\\ \text{Y}& \text{Sand}& \text{Pebbles}\end{array}$$ Which of the following methods can be used to separate the components of mixture X and Y?

• A. X- Filtration, Y- Decantation
• B. X- Sedimentation, Y- Filtration
• C. X- Filtration, Y- Handpicking
• D. X- Handpicking, Y- Distillation

Answer 1

The correct option is C X- Filtration, Y- Handpicking

$\bullet$ For mixture X: Chalk powder is insoluble in water. When the mixture is passed through filter paper, chalk powder gets collected on filter paper while water will pass through and can be collected in a container. Thus, the components of mixture X can be seperated by filtration.

$\bullet$ For mixture Y: In a mixture of sand and pebbles, a solid-solidmixture, the components differ in size and colour. So, they can be separated easily by handpicking.
