12. o Process of bringing destabilized colloidal particles together to allow them
to aggregate to a size where they will settle by gravity is flocculation
o Starch, Sodium polyalginate, Polyacrylamide etc. are examples of
flocculants.

o The amount of gas dissolved in water is directly
proportional to the partial pressure of that gas in
the vapor space above the water/gas interface.
This is known as Henry's law.
o Another important consideration of gas solubility is
Dalton's law, which states that the total pressure
of a mixture of gases is made up of the individual
pressures of those gases
