Question

Which of the following is a set of homogeneous mixtures?
1. Air
2. Mist
3. Sugar solution
4. Milk

• A. (i) & (ii)
• B. (ii) & (iii)
• C. (i) & (iii)
• D. (ii) & (iv)

Hint:

Homogeneous mixtures are uniform throughout, while heterogeneous mixtures have visibly distinct components.

Answer 1

The Correct Option is C

Step 1: Understand the definition of homogeneous and heterogeneous mixtures.
A homogeneous mixture is a mixture where the components are uniformly distributed and cannot be distinguished from each other.
A heterogeneous mixture has components that are not uniformly distributed and can be physically distinguished.

Step 2: Analyze each option:
(i) Air – Air is a mixture of gases that is uniformly distributed, so it is homogeneous.
(ii) Mist – Mist consists of tiny water droplets suspended in air, so it is a heterogeneous mixture.
(iii) Sugar solution – A sugar solution is formed when sugar dissolves completely in water, creating a uniform mixture, so it is homogeneous.
(iv) Milk – Milk is a colloidal mixture and is heterogeneous.

Step 3: From the analysis, only option (i) & (iii) are homogeneous mixtures. Thus, the correct answer is (3) (i) & (iii).
