CHEMISTRY – F4- ELECTROLYSIS
Lab Session – 2
Name:
Gas will not conduct electricity in any form
To conduct electricity in solid and liquid you need charged particles.
In solid: delocalised mobile electrons
In solutions: Free moving ions (cations and anions)
liquid
Solid
conductors
Insulators
Electrolyte
Non-Electrolyte
Most covalent compounds do not conduct electricity as they have no freely moving charged particles to
carry the current

Electrolysis of Molten Compounds
Lead(II) bromide is a binary ionic compound- it is a compound consisting of just two elements joined together by ionic
bonding
When these compounds are heated beyond their melting point, they become molten

How to predict the products
To predict the products of any binary molten compound
Step 1: first identify the ions present
Step 2:The positive ions will migrate toward the cathode
and the negative ions will migrate towards the anode
Step 3: cathode product will always be the metal and the product formed at the anode will always be the
non-metal
