A
M2O2 + H2O —–> M+ + OH- + H2O2
3
Q
Monoxide hydrolysis
A
MO + H2O ——> M+ + OH-
4
Q
Solvay process is used for
A
Manufacture of Na2CO3 from NH3
5
Q
Eq for solvay
A
NH3 + CO2 + H2O ——-> (NH4)2CO3
(NH4)2CO3 + H2O + CO2 —–> NH4HCO3
NH4HCO3 + NaCl ——> NaHCO3 + NH4Cl
NaHCO3 ———-> Na2CO3 + H2O + CO2
Recovery of NH3:
NH4Cl + Ca(OH)2 —-> NH3 + CaCl2 + H2O
