Suppose you stir a little baking soda into water until the water looks clear again. How could you prove to someone that the clear material is a solution, not a compound?
Answer (3)
You can prove this by letting the water evaporate or using a instrument that can measure the solids in a liquid.
A solution is defined as the substance formed due to addition of two or more number of substances. A solution is a homogeneous mixture.
And, homogeneous mixtures are always clear solution. Particles of a homogeneous solution never combine chemically with each other.
For example, when we dissolve baking soda in water then it will completely dissolve in water forming a clear solution.
So,** in order to determine that it is a solution we can let the water from the solution to evaporate.**
**This will leave behind the solute, that is, baking soda in the vessel. This will show that it is a solution. **
Whereas a compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.
For example, M g S O 4 is a compound and elements are present in 1:4 ratio.
Components of a compound can only be separated by chemical means and not by any physical means. ;
You can prove that the clear material is a solution, not a compound, by conducting an evaporation test, attempting to filter it, observing its reaction with acids, and noting its variable composition. These methods demonstrate that the baking soda retains its identity in a physical mixture with water. This shows it is a solution since it has not chemically combined into a compound.
