Washing soda, also denominated as soda ash or crystals and sodium bicarbonate, is a white odorless powder, which is immensely alkaline in nature and is manufactured from the raw materials such as Trona, which is cost-effective in nature. It is used significantly for water softening and regulating pH. Washing soda is formulated through three different processes: the Leblanc process, the Solvay process, and the Hou's process. The Solvay process is the most cost effective and is the preferred technique for the production of washing soda. Washing soda is extensively used as a cleaning agent. It can reverse alkalinity of a solution or a media and has excellent absorption capacity.
