WebTest the gas Bookmark Time to think on your feet, and design a test into the presence of CO 2, the catch is you can’t release the gas Design a piece of apparatus to allow you to obtain a sample of the gas without removing the gas jar from the water and demonstrate that the gas is carbon dioxide. This experiment should take one hour. Equipment WebProcedure Before the demonstration Line up five 250 cm 3 measuring cylinders in a tray. Add 75 cm 3 of water to the 75 cm 3 of 100 volume hydrogen peroxide solution to make 150 cm 3 of 50 volume solution. The demonstration Place about 1 cm 3 of washing up liquid into each of the measuring cylinders.
