Identify homogeneous mixtures from the following.
A. Soda water
B. Brass
C. Air
D. Soap solution
Solution
The mixture which contains all the chemicals or compounds in a single state is called homogeneous mixture. Nothing but the dissolved chemical is going to present in the same concentration throughout the solution.
Complete step by step answer:
- In the question it is asked to find the homogeneous mixture among the given options.
- Coming to the given options. Option A, soda water. Soda water contains water and dissolved carbon dioxide. But the problem is we can separate the dissolved carbon dioxide and water very easily.
- Therefore soda water is not a homogeneous mixture.
- Coming to option B, Brass. Brass is a mixture of copper and zinc with variable concentrations. But we cannot separate copper from zinc in the mixture. Therefore brass is an example for homogeneous mixture.
- Coming to option C, air. We know that air contains a lot of different gases and also contains dust particles and water in the form of moisture. Therefore air is not a homogenous mixture.
- Coming to option D, soap solution. Soap solution contains soap particles dispersed in water. But the soap particles are not going to distribute throughout the solution in a uniform manner. Therefore the soap solution is a heterogeneous mixture.
Therefore the correct option is B.
Note: Heterogeneous mixture is a mixture of chemicals in which all the chemicals are not going to present in a uniform manner. The examples for heterogeneous mixture are air, soap solution and soda water.
