Question

The table given below shows the properties of two unknown mixtures X and Y.

$$\begin{array}{ccc}\text{Mixture}& \text{Type of Mixture}& \text{Light scattering}\\ \text{X}& \text{Homogeneous}& \text{Does not scatter light}\\ \text{Y}& \text{Heterogeneous}& \text{Scatters light}\end{array}$$
Identify X and Y from the following.

• A. X: Sand and water, Y: Milk
• B. X: Sugar and water, Y: Sand and water
• C. X: Salt and water, Y: Sugar and water
• D. X: Milk, Y: Sand and water

Answer 1

The correct option is B X: Sugar and water, Y: Sand and water

Sugar and salt form homogeneous mixtures with water. The particle size here is too small to scatter light..

Sand and water form a suspension which is heterogeneous and scatters light.

Milk is a colloid which is heterogeneous. It also scatters light.
