Electrolysis of Molten Salts | GCSE Chemistry Practice
Electrolysis uses electricity to decompose ionic compounds into their elements.
Which ion moves to the cathode in the electrolysis of molten lead bromide?
What is Electrolysis of Molten Salts | Practice?
"The decomposition of a molten ionic compound using an electric current."
Which of these metals is the MOST reactive?
Zinc is extracted from its ore by heating with carbon. This is because...
Which of these metals will NOT react with dilute acid?
In electrolysis, where do the positive ions (cations) move to?
Molten Breakdown
Cathode: Negative electrode (where positive ions go).
Anode: Positive electrode (where negative ions go).
Molten salts: Ions are free to move and carry charge.
Lead Bromide ($PbBr_2$) splits into Lead ($Pb$) and Bromine ($Br_2$).
PANIC: Positive Anode, Negative Is Cathode. Simple and essential for exam marks!
