This week and next we will be studying solutions, as well as acids and bases. The science department considers this essential knowledge for your success in Biology next year, so please do your best to learn it. Remember, we are minimizing the content we are covering to help you through our current COVID-19 difficulties, but we are providing you with information that we hope you pay attention to.

Definitions
When making a solution, two parts are mixed together. These two parts are given the following names:

- The solvent is the substance there is more of.
Examples
- In a the ocean, water is the solvent, and salts are the solutes.
- In a soda, water is the solvent and sugar and flavorings are the solutes.
- In white gold, gold is the solute and platinum or palladium are the solutes.
- In air, nitrogen is the solvent, and oxygen, water vapor, and carbon dioxide are the solutes (and, unfortunately, often smoke or other pollution).
