Question

Raj's mother served him Horlicks with milk. But there were some particles of Horlicks left un-dissolved, and so he asked his mother to remove those particles. What method of separation should his mother use? Why? [2 MARKS]


Solution

Method: 1 Mark
Reason: 1 Mark

The best way to remove the Horlicks clumps is through filtration. While filtering the Horlicks solution, the powder clumps remain with the filter paper.

We choose filtration because Horlicks is a solution since it dissolves in milk. The dissolved particles of Horlicks go through the filter paper along with milk, and the undissolved portion remains on the filter paper, getting us exactly what we need.
