b.Hydrogen peroxide was measured 100ml using measuring cylinder and addeddistilled water until 500ml.
c.Manganese dioxide then was put into round bottom flask.
d.After that, put dropping funnel that filled with hydrogen peroxide on the round bottom flask.e.The rubber tube was put into the gas jar to collect the gas.f.Then, the hydrogen peroxide was dropped on manganese dioxide.
g.The gas collected was tested with glowing splinter.
h.The observations were recorded.
i.The procedure e until i repeated to get the pure oxygen gas.
Precaution: Hydrogen peroxide (H2O2) is corrosive.
