Hydrophilic : Dissolves in water (“water-loving”) Ex:
Hydrophobic : Does not dissolve in water (“water-fearing”) Ex:
Amphipathic : Has both hydrophilic & hydrophobic properties Ex:
Chemical reactions involving water also have specific terms:
Hydrolysis reaction :
Broken down putting in H2O ( adding ) or split using H2O.
Dehydration synthesis :
The formation of a molecule through the removal of H2O ( removing )
Acids, Bases, and Salts
Acids, bases and salts are substances that separate into specific ions when they are dissolved in water. Acid : a substance that dissolves in water and dissociates into one or more Hydrogen ions (H+) and one or more anions. An Acid is also known as a proton donor (Since H+ is a single proton).
Example:
Base : a substance that dissolves in water and dissociates into one or more Hydroxide ions (OH) and one or more cations. A Base is also known as a proton acceptor.
Example:
Salts : is a substance that dissolves in water and dissociates into cations and anions neither of which is H+ or OH-
