Concept Check! In your lab notebook, draw a large box. In this box, draw a molecular-level picture of a solution of barium nitrate (2 molecules) and sodium sulfate (5 molecules) in water before precipitation has taken place. In a second box, draw a molecular-level picture of the mixture after precipitation has taken place. Use simple circles to represent ions.

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.
