Please solve q.no 136
Dear student
136.
The Solvay process is an industrial process that uses limestone (CaCO3 ) to produce carbon dioxide (CO2 ) which reacts with ammonia (NH3 ) dissolved in brine (concentrated NaCl(aq)) to produce sodium carbonate.
Ammonium chloride(NH4Cl) formed as a byproduct. It reacts with calcium hydroxide to regenerate ammonia.
The principal by product is CaCl2.
Thus option (4) is incorrect
Regards

The Solvay process is an industrial process that uses limestone (CaCO3 ) to produce carbon dioxide (CO2 ) which reacts with ammonia (NH3 ) dissolved in brine (concentrated NaCl(aq)) to produce sodium carbonate.
The Solvay process results in soda ash (Na2CO3)) from brine (as a source of (NaCl)) and from limestone (as a source of calcium carbonate (CaCO3)).The overall process is:
- 2 NaCl + CaCO3 → Na2CO3 + CaCl2
Ammonium chloride(NH4Cl) formed as a byproduct. It reacts with calcium hydroxide to regenerate ammonia.
The principal by product is CaCl2.
Thus option (4) is incorrect
