About This Product
Current reaches the two carbon electrodes through crocodile clips, and the gases released rise into the test tubes suspended above them. In this Electrolysis cell, a piece of insulating material between the electrodes stops them short circuiting, while a piece of wood and rubber bands keep the test tubes in place.
Frequently Asked Questions
Q1. How are the gases collected in the Electrolysis Cells? The gases evolved are collected in two 75 x 10 mm test tubes suspended over the electrodes by a piece of wood and rubber bands.
Q2. What prevents the electrodes short circuiting? A piece of insulating material placed between the electrodes.
