Sodium carbonate, soda ash formula is Na2CO3 compound salt of carbonic acid, the white powder, no smell, can absorb moisture from the air. Dissolve in water has the effect is strong alkali when dissolved in water A little dissolved in alcohol. Found in the ash of many plant and seaweed (is called soda ash due to ash in English means the ashes) is a chemical used in many kinds of industry. Such as glass, ceramics, paper, detergent, soap, fixing water hardness.Sodium carbonate found in nature in the dry zone. Especially in the mineral resources resulting from the lake evaporated to dryness. In ancient Egypt, there was a การขุดแร่ called natron (natron) (which is the salt containing sodium carbonate (or soda ash) and sodium bicarbonate (baking soda) and sodium chloride (NaCl) and sodium sulfate mixed with little) from the bottom of the lake is dry. Near the Nile River and used in การทำมัมมี่ in year 2481 (AD) found 1938 carbonate ore size near green river river. Wyoming, USA, the US miner instead of chemical production processIn other countries, production of sodium carbonate by chemical treatment process called Solvay (Solvay process), which was discovered by Ernest. Solway, a Belgian chemical industry in 2009. 2404 (AD 1861) by turns. Sodium chloride (saline). Sodium carbonate Using ammonia and calcium carbonate (limestone) and the rest of the substance from the process, only the calcium chloride. Which is non-toxic, although it may cause irritation, and ammonia can also bring back work again. The Solvay process cost is lower than the traditional process. It is used in industrial sodium carbonate is widely used in the century 1900 sodium carbonate 90% produced using this method. And still in use today.The production of sodium carbonate by chemical process called the process เลอบลังก์ (Leblanc process), which was discovered by French chemist. The name Nicolas LeBlanc in 2005 2334 (AD 1791) using SEO.
