Question

Which of the following is a homogeneous mixture?

• A. Seawater
• B. Buttermilk
• C. Sugar Solution
• D. Starch Solution

Answer 1

The correct option is C

Sugar Solution

Explanation for correct option:

C. Sugar Solution

Homogenous mixture:

• “A mixture contains more than one substance (element and/ or compound) mixed in any proportion.”
• In a mixture when the substances are present in a uniform composition, these mixtures are called homogenous mixtures.
• Examples of homogenous mixtures are sugar solution and salt in water.

Explanation for incorrect options:

Heterogenous mixture:

• The mixture in which the composition is not uniform is known as a heterogeneous mixture.
• Mixtures in two or more phases are heterogeneous mixtures.
• Examples of heterogeneous mixtures are muddy water as well as oil in water.

Option A: Sea water is a heterogeneous mixture as there is bigger size impurities present which makes the mixture non-uniform in nature.

Option B: Buttermilk is a heterogeneous mixture due to its non-uniform composition.

Option D: The starch solution is a suspension.

Hence, the correct option is C i.e. sugar solution is a homogenous mixture.
