Title	: ELECTROLYSIS 1

Aim	: To observe the process of electrolysis

Apparatus : 
wires , 9 V battery , bulb , paper clips , watch glasses , 
solutions : sodium chloride , sulphuric acid , water
benzene , ethanol , silver nitrate , soln. x , copper sulphate

Directions : 
Set up a circuit using the paper clips as electrodes . Carefully
note the positive and negative poles . Using various chemical 
substances test to see if a current is conducted . Also observe 
the electrodes for bubbles , deposits and any other change in the
intensity of the light bulb . Tabulate your observation and draw 
reasonable conclusions about the nature of the chemical substances
and their ability to conduct a current .


Criteria    : OBSERVATION AND RECORDING ; 

20 mks for accuracy of observation .
re : light bulb , bubbles at electrodes , change in solution ,
