Q Type your question One of the chief uses of sodium carbonate has been in the conversion of $ \operatorname{Ca}(O H)_{2}(s) $ to concentrated aqueous solution of NaOH which in turn was used in the manufacture of soap. $ \boldsymbol{C a}(\boldsymbol{O H})_{2}(\boldsymbol{s})+\boldsymbol{2} \boldsymbol{N} \boldsymbol{a}^{+}(\boldsymbol{a q})+ $ $ \boldsymbol{C O}_{3}^{2-}(\boldsymbol{a q}) \rightleftharpoons \boldsymbol{C a C O}_{3}(\boldsymbol{s})+ $ $ \mathbf{2} N \boldsymbol{a}^{+}(\boldsymbol{a} \boldsymbol{q})+\mathbf{2} \boldsymbol{O} \boldsymbol{H}^{-}(\boldsymbol{a} \boldsymbol{q}) $ In $ 1775, $ in order to gain independence from the importation of natural $ N a_{2} C O_{3}, $ the French government offered a prize to anyone who could devise a process to prepare $ N a_{2} C O_{3} $ from NaCl A more economical process but based on the same principle was given by :

Accepted Answer

Solvay. The Solvay process is the economical industrial route for producing sodium carbonate from NaCl. It relies on converting brine into sodium bicarbonate, which is then heated to give Na2CO3.
