Describe a method of preparing oxygen without using a source of heat. mention a test of oxygen.
In long plz i want is fast.
Dear Student
Preparation of oxygen without the use of heat is by electrolysis of water:
The electrolysis of acidified water is carried out in a Hoffmann Voltameter. Oxygen is evolved at the positive electrode in the electrolysis.
A solution of barium hydroxide with nickel electrodes may also be used. However, on prolonged electrolysis an explosive mixture of oxygen and hydrogen may be evolved at the positive electrode.
