Electricity is a flow of charged particles (e.g. ions, electrons)
Covalent compounds do not conduct electricity because the electrons are fixed in the covalent bonds
Ions are fixed when ionic compounds are solid, meaning they can’t move so can’t conduct electricity.
However, when the compounds are molten or in aqueous solution, the ions (that are electrically charged) are able to move and carry charge.
Cations: positively charged ions (+) due to loss of electrons
Anions: negatively charged ions (-) due to gain of electrons
ELECTROLYSIS
Procedure
Power supply
PRODUCTS OF ELECTROLYSIS
Oxidation: loss of electron(s)
Reduction: gain of electron(s)
AIM
