Electrolysis - C2 AQA

* When an ionic substance is melted or dissolved in water, the ions are free to move about within the liquid or solution.

* Passin an electric current through ionic substances that are molten, for example lead bromide, or in solution breaks them down into elements. This process is called electrolysis and the substance that is brokwn down is called the electrolyte.

* During electrolysis, positively charged ions move the the negative electrode, and negatively charged ions move to the positive electrode.

* Electrolysis is used to electroplate objects. This may be for a variety of reasons and includes copper…
