WHAT IS LABORATORY PREPARATION OF OXYGEN
WHAT IS LABORATORY PREPARATION OF OXYGEN
Open in App
Solution
Laboratory preparation are as follows
- By heating oxygen containing compounds such as chlorates , nitrates and permangnents
KClO3→ 2KCl + 3O2
II. By thermal decomposition of the oxides of metals low in the electrochemical series and higher oxides of some metals
2Ag2O -→ 4Ag + O2
2HgO→2Hg +O 2
iii. hydrogen peroxide is readily decomposed into water and dioxygen by catalysis such as finely divided nickel , and MnO2
2H2O2 -→ 2H2O + O2
