The Solvay process is a multistep industrial process used to produce washing soda, Na2CO3(s). In the last step of the Solvay process, NaHCO3(s) is heated to 300°C, producing washing soda, water, and carbon dioxide. This reaction is represented by the balanced equation below. 2NaHCO3(s) + heat → Na2CO3(s) + H2O(g) + CO2(g) Write the IUPAC name for washing soda.
What is sodium carbonate
