experimental apparatus

Experimental Evidence - As the theory of chemical evolution started gaining more support, investigations were initiated by several scientists to establish the conditions under which, the simplest organic compounds were formed in the primitive earth. Two scientists, Stanley Miller and Haro..

"Electrolysis is the electrolytic dissociation and decomposition of an electrolyte (electrovalent substance), by the passage of a direct current or electricity through its aqueous or molten form." The process of electrolysis is not a simple chemical reaction of mix and match. As electricity i..

Kuhne's Tube(Glucose Solution + Yeast) The above apparatus is called the Kuhne's fermentation vessel. It is filled with 10% glucose solution along with yeast. The vertical tube is filled completely and the bulb is half-filled. After sometime, the level in the bulb goes up and the leve..

To Demonstrate Aerobic Respiration The apparatus shown is called the respiroscope that is used to demonstrate respiration. Few germinating seeds are taken in the bulb of the respirometer. The tube is inserted into a beaker containing mercury. A pellet of KOH is introduced into the set..

Take a test tube and add about 10 ml of 10% glucose solution in it. Add a pinch of dry baker's yeast into the glucose solution and cover the surface of the liquid carefully with an oily layer to prevent the contact with air. Fix a holed cork into the mouth of the test tube and pass a delivery tube ..

To Demonstrate Aerobic Respiration - Put some germinating seeds in a conical flask. With the help of a thread suspend a small tube containing KOH in the flask. Through the hole of the cork pass a glass tube bent twice at right angles. One end of the tube is in the flask while the other end is in th..
