Answer 1

Answer:

1. Solution

2. Colloid

3. Suspension

4. Colloid

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.
