                     SODIUM CARBONATE, SODA ASH, FOR TREATMENT, WHITE POWDER
     Sodium carbonate or soda ash, the chemical formula Na2CO3, is a salt compound of carbonic acid. It has a white powder, odorless, able to absorb moisture from the air well. Soluble in water Has a strong alkalinity when dissolved in water Slightly soluble in alcohol Found in the ash of many plants and seaweed. (Hence the name Soda Ash, because ash in English means ash) is a chemical used in many industries such as glass, ceramics, paper, detergent, soap.
     sodium carbonate Found in nature in arid areas. Especially in the mineral deposits that evaporate the lake In ancient Egypt There are mines called natron (which is a salt consisting of sodium carbonate (or soda ash) and sodium bicarbonate (baking soda) and sodium chloride (table salt) and sodium sulfate. Slightly mixed) from the bottom of the dry lake Near the nile And used in mummification in the year 2481 (1938) found a large mineral sodium carbonate near the Green River, Wyoming, USA, allowing the United States to extract minerals instead of chemical production.
      In other countries, the production of sodium carbonate is done by a chemical process known as Solvay process, which was discovered by Ernest Solvay, a Belgian chemical industrialist in 1861, by changing sodium chloride (brine) to sodium carbonate by Use ammonia and calcium carbonate (limestone) and the remaining substances from the process only Calcium Chloride Which is non-toxic, although it can cause irritation and ammonia can still be reused. Resulting in the Solvay process having a much lower production cost than conventional methods Therefore is widely used in the sodium carbonate industry In the 1900s, 90% of the sodium carbonate produced using this method And still in use today
         In the past, the production of sodium carbonate was done by a chemical process called The Leblanc process, which was discovered by a French chemist Nicholas Leblanc in 1791, using sodium chloride (table salt) acid. Sulfuric (sulfuric acid), calcium carbonate (limestone) and charcoal, but hydrochloric acid (hydrochloric acid) caused by this process Causing air pollution And calcium sulfide Left over from the process causing environmental problems But since sodium carbonate is a basic chemical in many industries Resulting in the production of sodium carbonate by this process And the main process until the years 1880 - 1890 (between 1880 - 1890). After the discovery of the Solvay process for over 20 years, the calcium carbonate factory using the process The final Lebranc closed down in 1920.
