Water and Inorganic Ions

Elctromagnetic attraction between a pair of polar molecules, such as water where the hydrogen atoms are slighlty positive and the oxygen atom is slightly negative, this causes bonds to form of hydrogens of one molecule ot oxygens to others. 

Chemical process by which 2 molecules are joined together to make a larger more complex molecule releasing  oxygen as doing so.

The opposite to condensation. A large molecule splits into 2 smaller molecules using up water in the process.
