Interpretation:The conclusion made about the two liquids based on the given findings should be explained.
Concept Introduction:A compound that is made up of two or more chemical components that are not chemically linked with each other is said to be a mixture.
Answer to Problem 20SP
Container A has a homogenous mixture whereas container B has a heterogeneous mixture.
Explanation of Solution
Given information:
Liquids A and B are both clear liquids. They are poured into open containers and left to evaporate. When the evaporation process is finished, there is a white solid in container B but no solid in container A.
The mixtures are classified based on the distribution of components:
- Homogenous mixture: A mixture is said to be homogenous when its composition is uniform throughout. For example, the mixture of alcohol and water.
- Heterogenous mixture:A mixture is said to be heterogenous when its composition is not uniform throughout. For example, the mixture of oil and water.
Since there is no solid in container A after the evaporation, it means the composition in container A is uniform throughout. Thus, it makes a homogenous mixture. Whereas there is a white solid in container Bafter the evaporation, which means the composition in container B is non-uniform throughout and thus it makes a heterogeneous mixture.
