Question

The alloy bronze contains copper and tin. This is a:

• A. Homogeneous mixture
• B. Heterogeneous mixture
• C. Solid solution of two immiscible metals
• D. Pure substance

Answer 1

The correct option is A

Homogeneous mixture

• Alloys is a substances formed from the combination of two or more metals.
• Alloys can also be formed combination of metals and other elements.
• Alloys are known to feature metallic bonding.

Example-Steel.

Explanation of correct option:

• Homogeneous Mixture: A mixture in which different constituents are mixed uniformly is called a homogeneous mixture.
• Examples: alloys such as brass, bronze, etc. are homogeneous solid solutions of metals and air is a homogenous mixture of gases.

Explanation of incorrect options:

(B) - Heterogeneous mixture

Heterogeneous Mixture: A mixture in which different constituents are not mixed uniformly is called a heterogeneous mixture.

Examples: A mixture of sand and salt, iron powder and sulfur powder, soil, etc. are examples of heterogeneous mixtures.

(C) - Solid solution of two immiscible metals

A solid solution of two immiscible metals forms heterogeneous mixtures.

(D) -Pure substance

Pure substances: Only one type of particle are present (no impurities)

Example: Elements and Mixtures

Hence, Option (A) is the correct option.
