Sodium carbonate (also known as washing soda or soda ash), Na₂CO₃, is a sodium salt of carbonic acid. It most commonly occurs as a crystalline heptahydrate which readily effloresces to form a white powder, the monohydrate. 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.

Uses

• Sodium carbonate's most important use 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, sodium carbonate can be used to form a transparent non-crystalline material, commonly known as glass.

• In chemistry, sodium carbonate is often used as an electrolyte. This is because electrolytes are usually salt based, and sodium carbonate acts as a very good conductor in the process of electrolysis.

• Domestically 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 or Sal Soda^[1] 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.

Occurrence

Sodium carbonate is soluble in water, but can occur naturally in arid regions, especially in the mineral deposits (evaporites) formed when seasonal lakes evaporate. Deposits of the mineral natron, a combination of sodium carbonate and sodium bicarbonate, have been mined from iuguguggdry lake bottoms in Egypt since ancient times, when natron was used in the preparation of mummies and in the early manufacture of glass. Sodium carbonate has three known forms of hydrates: sodium carbonate decahydrate, sodium carbonate heptahydrate and sodium carbonate monohydrate.

Production

Mining

Trona, hydrated sodium bicarbonate carbonate (Na₃HCO₃CO₃·2H₂O), is mined in several areas of the United States and provides nearly all the domestic sodium carbonate. Large natural deposits found in 1938 near the Green River, Wyoming have made mining more economical than industrial production in North America.

Barilla and Kelp

A number of "halophyte" (salt tolerant) plant species and of seaweed species can be processed into an impure form of sodium carbonate, and these sources predominated in Europe and elsewhere until the early 19^th Century. The land plants or the seaweed were harvested, dried, and burned. The ashes were then "lixiviated" (washed with water) to form an alkali solution. This solution was boiled dry to create the final product, which was termed "soda ash;" this very old name refers to the archetypal plant source for soda ash, which was the small annual shrub Salsola soda ("barilla plant"). A halophyte is a plant that naturally grows where it is affected by salinity in the root area or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. ... Sodium carbonate or soda ash, Na2CO3, is a sodium salt of carbonic acid. ... Binomial name Salsola Soda Weinm. ...

The sodium carbonate concentration in soda ash varied very widely, from 2-3% for the seaweed-derived form ("kelp"), to 30% for the best barilla produced from halophyte plants in Spain. Plant and seaweed sources for soda ash, and also for the related alkali "potash," became increasingly inadequate by the end of the 18^th Century, and the search for commercially viable routes to synthesizing soda ash from salt and other chemicals intensified.^[3] Insert non-formatted text hereLink title Families Alariaceae Chordaceae Laminariaceae Lessoniaceae Phyllariaceae Pseudochordaceae For other uses, see Kelp (disambiguation). ...

Because the Solvay process recycled its ammonia, it consumed only brine and limestone, and had calcium chloride as its only waste product. This made it substantially more economical than the Leblanc process, and it soon came to dominate world sodium carbonate production. By 1900, 90% of sodium carbonate was produced by the Solvay process, and the last Leblanc process plant closed in the early 1920s.

Hou's Process

Developed by a Chinese chemist Hou Debang in 1930s. It is the same as the Solvay process in the first few steps. But instead of treating the remaining solution with lime, carbon dioxide and ammonia is pumped into the solution and sodium chloride is added until it is saturated at 40 degrees C. Then the solution is cooled down to 10 degrees C. Ammonium chloride precipitates and is removed by filtration, the solution is recycled to produce more sodium bicarbonate. Hou's Process eliminates the production of calcium chloride and the byproduct ammonium chloride can be used as a fertilizer. Hou's Process is the most common current process in the world to produce sodium carbonate. Ammonium chloride or Sal Ammoniac (chemically ammonium chloride (NH4Cl); also nushadir salt, zalmiak, sal armagnac, sal armoniac, salmiakki, salmiak and salt armoniack) is, in its pure form, a clear white water-soluble crystalline salt with a biting taste. ...
