Question

Four students were asked to add water to glucose powder, milk, sand and soil separately in four beakers. Classify the mixtures as true solution, colloid and suspension.

Answer 1

1 solution
2 colloid
3 suspension
4 colloid

Answer 2

Explanation:

When two or more substances completely dissolve in a solution then it forms a homogeneous mixture and this solution is known as true solution.

When microscopically a substance is suspended into another liquid throughout the solution then it is known as colloid.

When particles of solute present in a solution suspend after their addition into the solution then that solution is known as suspension.

Therefore, given mixtures are classified as follows.

• Water and glucose powder will form a true solution.

• Water and milk will form a colloid.

• Water and sand will form a suspension.

• Water and soil will form a suspension.
