Question

The size of particles in a solution is :

• A. Smaller than ${10}^{-7}$ cm
• B. Larger than ${10}^{-5}$ cm
• C. Between ${10}^{-5}$ and ${10}^{-8}$ cm
• D. Smaller than ${10}^{-5}$ cm.

Answer 1

The correct option is A

Smaller than ${10}^{-7}$ cm

The explanation for the correct answer:

1. Solution: A solution is a homogeneous mixture of two or more substances.
2. The size of particles of a solution is too small to be individually seen by naked eyes.
3. The particles of a solution are smaller than ${10}^{-7}$cm.

The size of particles in a solution is Option(A) Smaller than ${10}^{-7}$ cm
