Question

write an equation to show how oxygen can be obtained from sodiumtrioxonitrate(4)​

Answer 1

Answer:

Oxygen can be prepared in a number of ways in the laboratory. These include:

(a). Heating a mixture of potassium trioxochlorate(V), KClO3 and maganese(IV) oxide, MnO2.

The MnO2 acts as a catalyst. The reaction is actually the decomposition of KClO3.

2KClO3(s) → 2KCl(s) + 3O2(g)

(b). The decomposition of hydrogen peroxide, H2O2 using manganese(IV) oxide - this does not require heating.

Hydrogen peroxide is added drop wisely unto MnO2.

2H2O2(aq) → 2H2O(l) + O2(g)

Or by the drop wise addition of hydrogen peroxide on acidified KMnO4

5H2O2(aq) + 2KMnO4(aq) + 3H2SO4(aq) → K2SO4(aq) + 2MnSO4(aq) + 8H2O(l) + 5O2(g)
