Preparation of washing soda by solvay’s process

  • The Solvay process is extensively used for industrial preparation of sodium carbonate (soda ash). The process is named after Ernest Solvay who developed the process during the 1860s.
  • Carbon dioxide reacts with the dissolved ammonia to form ammonium carbonate followed by ammonium hydrogen carbonate.

2NH3 +H2O + CO2 —> (NH4)2CO3

(Ammonia)                 (Ammonium Carbonate)

(NH4)2CO3 + H2O + CO2 –> NH4HCO3

(Ammonium Carbonate)       (Ammonium hydrogen carbonate)

NH4HCO3       +          NaCl  –>   NH4Cl     +    NaHCO3

Sodium hydrogen carbonate crystal separates. These are heated to give sodium carbonate.

     2 NaHCO3       –>      Na2CO3 + CO2 + H2O

But this process cannot be used to prepare potassium due to the high solubility of potassium bicarbonate and hence difficult to be precipitated by adding ammonium bicarbonate to a saturated solution of potassium

Atomic and Ionic Radii of alkaline earth metal

  • The atomic and ionic radii of the alkaline earth metals are smaller than alkali metals due to the increased nuclearcharge in these elements.
  • Theatomic and ionic radii increase with increase in atomic number within a group.
