Question

how is washing soda manufactured by solvay's process ?give theory only​

Answer 1

Answer:

make me brain list

Explanation:

2NH3(s)+co2(g)>>(NH4)CO3

(NH4)CO3+CO2+H2O>>2NH4HCO3

2NH4HCO3+NaCl>>>NAHCO3+NA4Cl

NH4+HEAT>>>>Na2Co3+H20+Co2

Answer 2

Preperation 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

• (NH₄)₂CO₃ + H₂O + CO₂ ⇒ NH₄HCO₃

• NH₄HCO₃ + NaCl ⇒ NH₄Cl + NaHCO₃

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

• 2NaHCO₃ ⇒ 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.
