Question 1

Superoxide hydrolysis

Answer 1

MO2 + H2O —–> H2O2 + M+ + O2 + OH-

Question 2

Peroxide hydrolysis

Answer 2

M2O2 + H2O —–> M+ + OH- + H2O2

Question 3

Monoxide hydrolysis

Answer 3

MO + H2O ——> M+ + OH-

Question 4

Solvay process is used for

Answer 4

Manufacture of Na2CO3 from NH3

Question 5

Eq for solvay

Answer 5

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
