How did electrolysis start?

Chemists started putting electrodes – positive and negative electrical terminals connected to a power source via wires – into solutions to see what would happen when they connected a direct-current battery.

Positive and Negative electrodes were places into solutions connected to a power source to see what would happen

 

Here are some examples of what happened:

Example 1 – Electrolysis of water and sodium chloride

Example 2 – Electrorefining copper 

Example 3 – Electrolysis of water 

Example 4 – Electroplating with silver
