Imagine carbon dioxide (CO2) gas is generated by reacting aqueous sodium bicarbonate with aqueous acetic acid. As the gas bubbles from the surface of the solution, the gas is trapped by a large test tube which was turned upside down and the end submerged below the level of the solution. When you analyze the gas trapped in the tube, you find that it contains not only carbon dioxide but water as well. (i) Explain why water vapor is present in the gas sample in the tube. Be sure to include an appropriate, labeled diagram.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
