Question

An electrolysis experiment
Electrolysis is used to break a simple compound into its component elements. For example, electrolysis will break silver and chlorine elements from which it is made. In this activity, you will observe how electrolysis breaks a simple compound.
Dissolve some copper chloride (CuCI2) powder in water. Subject the solution to electric current by using a 9 volt cell as shown. Attach nails to each of the wires leading to negative and positive terminals of the cell.

Observe what happens on the two electrodes and answer the questions.
1. Does the nail attached to the negative electrode show any change?
2. On which electrode will the copper from the solution collect?
3. What will collect at the positive electrode?
4. is there any change in the colour of the solution as the time progresses?
