1.	Starting with sodium chloride how would you proceed to prepare sodium carbonate? Mention the steps only.
Answer» SOLUTION :Sodium carbonate may be obtained by PASSING `CO_2` through ammoniacal brine (SOLVAY ammonia soda PROCESS) when `NaHCO_3` gets precipitated. This on heating gives `Na_2CO_3`. `NACL + NH_3 + CO_2 + H_2O to NaHCO_3 darr + NH_4Cl` `2NaHCO_3 to Na_2CO_3 + CO_2 + H_2O`
