WebHydrogen peroxide is an economical but powerful and environmentally friendly oxidizing agent that has found many uses in the chemical industry for the manufacture of organic compounds. Due to its low molecular weight, hydrogen peroxide is a more efficient oxidizing agent on a weight per weight basis than potassium dichromate or permanganate. WebThe demonstration. Place about 1 cm 3 of washing up liquid into each of the measuring cylinders. To each one add the amount of catalyst specified above. Then add 25 cm 3 of 50 volume hydrogen peroxide solution to each cylinder. The addition of the catalyst to each cylinder should be done as nearly simultaneously as possible – using two ...
