What is sodium carbonate?</h3>
The sodium carbonate, the inorganic substance with the formula, is also known as washing soda, soda ash, and soda crystals.
All of the forms are water-soluble, odourless, white salts that produce slightly alkaline solutions in water. In the past, it was recovered from the ashes of plants that were raised in soils high in salt.
The term "soda ash" originated to refer to sodium carbonate because the ashes of these sodium-rich plants were probably distinct from the wood ashes that were originally used to make potash. The Solvay technique is used to produce it in large amounts from limestone and sodium chloride.
