This measurment is use for separate the solution by the reaction of electric charge and particle of solution. It can explain Michael Faraday's the splitting water with electricity rule. The water reciever is a glass tube, has a bag for recieve water link to 50 ml. 2 burettes, 14 x 52 cm. by total sizes. 2 electrodes used with input 6 - 9 V. DC. Gas from this system have to contians at burettes and can check kind of those gas by accessories equipment is electric transformer AC/DC (2019252) and crocodile clip leads (2019110).
