Electrolysis
Electrolysis is the process by which ionic substances are broken down into simpler
substances using electricity
...
What is electrolysis?
Ionic substances contain charged particles called ions
...
Electrolysis is the process by which ionic substances are decomposed (broken
down) into simpler substances when an electric current is passed through them
...
Ions are free to move
when an ionic substance is dissolved in water or when melted
...
Here is what happens during electrolysis:
Positively charged ions move to the negative electrode during electrolysis
...
Negatively charged ions move to the positive electrode during electrolysis
...
The substance that is broken down is called the electrolyte
...
To test for
conductivity, include a sample of the substance in a circuit that contains a source
of direct current (eg a cell or power pack) and a bulb or an ammeter
...
Definitions:
Ionic substances- form when a metal reacts with a non-metal/ They contain
charged particles called ions
...
Ion- positively or negatively charged particles- eg positively charged hydrogen,
sodium and potassium atoms
...
Molten- molten means reduced to liquid form by heating
...
Reduction- A reaction in which oxygen is removed from a substance
...
