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.
