Question

Identify homogeneous mixtures from the following.

• A. Soda water
• B. Brass
• C. Air
• D. Soap solution

Answer 1

The correct option is B

Brass

The explanation for the correct answer:-

Option (B) Brass

1. Homogeneous mixture: A Homogeneous mixture is a gaseous liquid or solid mixture that has the same proportions of its components throughout the given sample.
2. Brass is a homogeneous mixture of two metals and cannot be separated into components by physical methods.
3. Hence, option (B) is correct.

Option (A) Soda water

1. Soda water is a mixture of liquid and gas so it can be considered a heterogeneous mixture.
2. Hence, option (A) is also correct.

The explanation for the incorrect answer:-

Option (A) Soda water

1. Heterogeneous mixture: A heterogeneous mixture is a solution or mixture where the composition of the mixture is not uniform.
2. Soda water is a mixture of liquid and gas so it can be considered a homogeneous mixture, but can be considered a heterogeneous mixture when gas bubbles are physically distinct.
3. Hence, option (A) is incorrect.

Option (C) Air

1. Air is composed of various gases and dust particles sometimes it is non-uniform and cannot be distinguished so it is considered a Heterogeneous mixture.
2. Hence, option (C) is incorrect.

Option (D) Soap Solution

1. Soap solution is a heterogeneous mixture because the soap particles are not uniformly distributed in the water.
2. Hence, option (D) is incorrect.

Therefore, Brass is a homogeneous mixture of two or more metals, Hence option (B) is correct.
