Sodium carbonate (also known as washing soda or soda ash), is
a sodium salt of carbonic acid. It has a cooling alkaline taste, and
can be extracted from the ashes of many plants. It is synthetically
produced in large quantities from table salt in a process known as
the Solvay process.
The most important use for sodium carbonate is in the chemical
make-up of glass. When heated at very high temperatures, combined
with sand (SiO2) and calcium carbonate (CaCO3), and cooled very
rapidly, glass is produced.
Sodium carbonate is also used as a relatively strong base. For example,
it 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 pH.
In domestic use, it is used as a water softener. It competes with the
magnesium and calcium ions 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 or Sal Soda in the detergent section of
stores, it effectively removes oil, grease, and alcohol stains. Sodium
carbonate is also used as a de-scaling agent in boilers such as found in
coffee pots, espresso machines, etc.
Sodium carbonate may be used for safely cleaning silver. Aluminum foil
is added to a glass or ceramic container, and covered with hot water and
some sodium carbonate. Silver items are dipped into this "bath" to clean
them, making sure the silver makes contact with the aluminum foil. Finally,
the silver is rinsed in water and allowed to dry.
Inhalation of dust may cause irritation. Slightly toxic by
ingestion. May cause severe irritation to eyes.
