name: Sodium Carbonate
Synonym name: Soda Ash
Uses: In chemicals industry, wood
pulp and paper industry, glass, soap and detergents manufacturing industry.
The manufacture of glass is one of the
most important uses of sodium carbonate. When it is combined with silica (SiO)
and calcium carbonate (CaCO) and heated to very high
temperatures, then cooled very rapidly, glass is produced. This type of glass
is known as soda lime glass
carbonate is also used as a relatively strong base in various settings. For
example, sodium carbonate is used as a pH regulator to maintain stable alkaline
conditions necessary for the action of the majority of developing agents.
It is a common additive in municipal pools used to neutralize the acidic
effects of chlorine and raise pH2
In cooking, it is
sometimes used in place of sodium hydroxide for. These
dishes are treated with a solution of an alkaline substance in order to change
the pH of the surface of the food and thus improve browning.
In taxidermy, sodium
carbonate added to boiling water will remove flesh from the skull or bones of
trophies to create the "European skull mount" or for educational
display in biological and historical studies.
use, it is used as a water softener
during laundry. It competes with the ions magnesium and calcium in hard water and prevents
them from bonding with the detergent being used. Without using washing soda,
additional detergent is needed to soak up the magnesium and calcium ions.
Called Washing Soda, Soda crystals or Sal Soda
in the detergent section of stores, it effectively removes oil, grease, and
alcohol stains. Sodium carbonate is also used as a descaling agent in boilers
such as found in coffee pots, espresso machines, etc.
