b. What is a solution? A homogeneous mixture of one or more solutes dissolved in a substance c. Give an example of a solution that does not involve a solid being dissolved in a liquid. Explain how this is a solution.

**b. What is a solution?** <br />A solution is a homogeneous mixture of one or more solutes dissolved in a substance (the solvent).<br /><br />**c. Example of a solution that does not involve a solid being dissolved in a liquid:** <br />An example is air, which is a solution of gases. For instance, oxygen (solute) is dissolved in nitrogen (solvent). This is considered a solution because the gases are uniformly mixed at the molecular level, forming a single-phase homogeneous mixture.
