Question

Which of the following is/are not homogeneous mixtures/solutions?
(i) Water in alcohol
(ii) Sulphur in carbon disulphide
(iii) Water in oil
(iv) Vinegar
(v) Sand in water

• A. (i), (ii) and (iii)
• B. (ii), (iii) and (iv)
• C. (iii) and (v)
• D. (iv) and (v)

Answer 1

The correct option is C (iii) and (v)

The mixture in which the substances are completely mixed together and are indistinguishable are called homogeneous mixtures.
(i) Water and alcohol are miscible with each other and forms a homogeneous mixture.
(ii) Sulphur dissolves completely in carbon disulphide, therefore, forms a homogeneous mixture.
(iii) Water and oil are immiscible liquids and forms a heterogeneous mixture.
(iv) Vinegar is a homogeneous mixture of water and acetic acid.
(v) A mixture of sand in water is an example of a heterogeneous mixture.
Hence, the correct answer is option (c).
