Featured this week: example questions for Electrolysis

New example questions from the library every Monday. Updated on 12 October 2026.

What happens to a balloon filled with hydrogen?
It rises up It sinks down It stays floating It gets heavier
What do we call splitting water using electricity?
Electrolysis Boiling Freezing Mixing
How can you collect the gases?
With an upside-down glass With your hands With a net With a spoon
Does the water get warmer during electrolysis?
Yes, a little No, it gets colder It becomes ice cold The temperature doesn't change
What happens when you pass electricity through water?
The water splits into two parts The water gets warmer The water turns blue The water disappears
How many electrodes do you need for electrolysis?
Two One Three Four
At which electrode is hydrogen released?
At the negative electrode At the positive electrode At both electrodes At neither of them
What do you need to carry out electrolysis?
Electricity and water Only water Only electricity Fire and water
Create a electrolysis treasure hunt for Ages 5-6
What happens if you turn off the power during electrolysis?
The process stops The process is faster The process slows down Nothing happens
What material is commonly used for electrodes in electrolysis?
Carbon (graphite) Wood Plastic Glass
What do you call the process in which a substance is split by electricity?
Electrolysis Photosynthesis Condensation Evaporation
What do you need to perform electrolysis?
Electric current and a liquid Water only A magnet and salt Only a battery
What property does hydrogen gas have that can make it dangerous?
It is highly flammable It is very heavy It smells terrible It is toxic to inhale
What do you call the negative electrode?
Cathode Anode Elektron Neutron
What property must a liquid have for electrolysis?
It must be able to conduct electricity It must be warm It should be blue It must taste sweet
What form of energy is produced when hydrogen is burned?
Heat and water Light and oxygen Sound and steam Magnetism and power
Create a electrolysis treasure hunt for Ages 11-12
What is the main advantage of electrolysis over other separation methods?
Very high purity of the product Very low costs Very high speed No electricity required
Why are carbon electrodes popular in electrolysis?
They are chemically inert and conduct well They are the cheapest They are the lightest They have the most beautiful colour
Which metal can NOT be extracted by electrolysis?
Gold (mostly mined mechanically) Aluminium Sodium Magnesium
Which industry makes extensive use of electrolysis for metal extraction?
The aluminium industry The food industry The textiles industry The pharmaceutical industry
What is the difference between electrolysis and electroplating?
Electroplating is a specific application of electrolysis Electrolysis is a specific application of electroplating They are the same process They have nothing to do with each other
What is the difference between electrolysis and a galvanic cell?
In electrolysis, energy is supplied, in galvanic cells, energy is generated There is no difference Electrolysis does not use electrodes Galvanic cells do not use electrolyte
What property of aluminium makes electrolysis necessary for extraction?
It is highly reactive and difficult to reduce It is very heavy It is magnetic It is toxic
Why is electrolysis of molten salts easier than of solutions?
As no competing reactions with water occur Because it is cheaper Because it is faster Because less energy is needed
Create a electrolysis treasure hunt for Ages 13-14
In the electrolysis of copper sulphate solution with copper electrodes, things happen at the anode:
Copper dissolves Copper knocks down Oxygen is released Hydrogen is released
In which electrolysis is chlorine produced industrially?
Electrolysis of saltwater Electrolysis of hydrochloric acid Electrolysis of potassium chloride Electrolysis of magnesium chloride

0.635 g 1.27 grams 2.54 grams 0.318 g
Which statement about the efficiency of electrolysis is correct?
Efficiency is always less than 100% Efficiency can be higher than 100% Efficiency is always exactly 100% Efficiency plays no role in electrolysis
In which industry is electrolysis NOT used?
Textile industry Aluminium production Chlorine production Galvanising
How much time is needed to deposit 10 grams of copper at a current of 5 amps?
About 1012 seconds About 506 seconds About 2024 seconds About 304 seconds
What is overpotential in electrolysis?
Additional voltage required above theoretical value The maximum voltage that may be used The voltage difference between the electrodes The tension released as heat
