5 Electrolysis Flashcards
Electrolysis (split)
Electro -> Electricity -> Flow of electrons
Lysis -> Pertaining to(maybe referring to the ions and electrons)
Describe an electrolytic cell:
- A non-conducting vessel
2. Containing the electrolyte (Aq or Fused)
Electrolytic cell must have a conducting vessel.
True or False.
False.
Anode is connected to the ____ terminal.
Cathode is connected to the _____- terminal of the battery.
Positive. Negative.
Define electrolysis
- Decomposition of a chemical compound
- Aqeous or Fused State
- Passage of direct electric current
- Results in discharge of ions as neutral atoms in respective electrodes.
Electrolysis is a physical or chemical change?
It is also a ____ reaction.
Chemical Change. Redox.
Electrolytes are always _____.
But its examples are not always this.
Ionic Compounds
Idiotic
Define Electrolytes:
Chemical compounds which conduct electricity in fused or aq state, due to the flow of current through it.
Define non-electrolytes:
Chemical compounds which do not conduct electricity in the fused or aq state.
Do ont undergo chemical decomposition.
NOn-Electrolytes are always _____.
But its examples are not always this.
Covalent compounds
Particles in Electrolytes
Ions only, Ions and Molecule only
Particles in non-electrolytes
Molecules
Examples of electrolytes:
All strong + weak electrolytes.
Examples of non-electrolytes:
Non-polar covalent compounds and aq solution of non-polar covalent compounds
Strong electrolytes:
- Electrolytes that allow large amount of electricity to pass through it.
- Good conductors of electricity
- Almost completely dissociated.
Particles in strong electrolytes are ___-.
Particles in weak electrolytes are ___-.
Ions only.
Ions and Unionized molecules.
Examples of strong electrolytes
All strong acids and bases and salts of strong acids.
Examples of weak electrolytes
All weak acids and bases and salts of weak acids.
Electrolytic cell definition. (device)
Device -> Electrolysis carried out.
Electrodes.
Electrolytic solution.
Electrylitic cell is also called
Voltameter.
Why electrodes?
They allow the current to enter or leave the current?
Electrodes can be (material)
Metal or Carbon
When are graphite or Carbon electrodes used
When the products formed reacts with the metallic electrode.
Depending on the connection to the battery, they are classified as
Anode or Cathode
