Electrolysis of Brine | GCSE Chemistry Practice
The electrolysis of concentrated sodium chloride solution (brine) produces three useful industrial products.
Name the three products of the electrolysis of brine.
What is Electrolysis of Brine | Practice?
"The electrolysis of concentrated sodium chloride solution to produce chlorine, hydrogen, and sodium hydroxide."
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?
Brine Products
Chlorine gas: Produced at the anode (used for bleach/plastics).
Hydrogen gas: Produced at the cathode (used for margarine/fuel).
Sodium Hydroxide solution: Left in the container (used for soap).
Chlorine is a halogen; hydrogen is produced because it is less reactive than sodium.
Exam Prep: This is a classic "6-marker" topic. Make sure you can name all three products and their uses.
