# BIOL 01113 Vocab 2 - Aidan Sharpe ### Solution A solution is the result of one or more solutes dissolving into a solvent. For example, salt can be dissolved into water to create a salt water solution. ### Solute A solute is a compound that can be dissolved. For example, in salt water, salt is the solute. ### Solvent A solvent is a compound that can dissolve other compounds. For example, in salt water, water is the solvent. ### Hydrogen bonds Hydrogen bonds are a type of weak inter-molecular bond that occurs in polar molecules, where the hydrogen has a slight positive charge. ### Hydrophilic A type of material that water is attracted (sticks) to. ### Hydrophobic A type of material that repells water. ### Acid A compound with a low pH (<7 at standard temperature) that has a high concentration of hydrogen ions (H$^+$). ### Base A compound with a high pH (>7 at standard temperature) that has a low concentration of hydrogen ions (H$^+$). ### pH The pH is a logarithmic scale that measures the acidity or basicity of a compound. The lower the pH, the more acidic. The higher the pH, the more basic. ### Buffer A substance that resists change in pH.
