Q7.
In industry sodium carbonate is made from sodium chloride solution and calcium carbonate in the
Solvay Process
The overall equation for the Solvay Process is
2NaCl + CaCO3 Na2CO3 + CaC2
Calculate the maximum mass of sodium carbonate that could be formed by reacting 40 kg of calcium
carbonate with an excess of sodium chloride solution. (Relative formula masses: Caco, = 100;
Na2CO3 = 106)
