Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda.
The Leblanc process was an early industrial process for making soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate.
By baking the sodium bicarbonate, water vapor and carbon dioxide gas are released, and what is left is the alkaline sodium carbonate. Only a very small amount of the resultant sodium carbonate is used in the preparation of McGee's pasta dish, just 1 teaspoon of it to 1-1/2 cups of semolina flour.
The sodium sulfate is afterwards fired with calcium carbonate and coal. Sodium carbonate can be extracted from this mixture by washing the mixture with water. [2] Until the rise of the ammonia-soda process, which has better economics, the Leblanc process was used extensively making the United Kingdom the lead in alkali production. By the early ...
Instead of treating the remaining solution with lime, carbon dioxide and ammonia are pumped into the solution, then sodium chloride is added until the solution saturates at 40 °C. Next, the solution is cooled to 10 °C. Ammonium chloride precipitates and is removed by filtration, and the solution is recycled to produce more sodium carbonate.

During the early years of European settlement of the Americas, settlers used soda or pearl ash, more commonly known as potash (pot ash) or potassium carbonate, as a leavening agent (the forerunner to baking soda) in quick breads. [13] By 1824, The Virginia Housewife by Mary Randolph was published containing a recipe for Soda Cake. [14]
