Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What factors affect the quantity of elecrticity passing through an electrolytic cell?
current and time/ I & t
What is the value of Faraday's constant?
96,500 C
What are examples of ions found at the cathode?
cations--Pb2+, Na+, Cu2+
What are examples of ions found at the anode?
anions--Cl-, OH- , SO42-
What type of electrolyte is pure water? Why?
weak because it only partially ionizes in H+ and OH- ions
Name 2 examples of strong electrolytes
any strong acid/alkali; molten/aqueous ionic compound-H2SO4, NaOH
What type of reaction occurs at the cathode?
reduction
What type of reaction happens at the anode
oxidation
True / False:    The cathode is the negative electrode.
True
True / False:   The anode is the negative electrode.
False
What is electrolysis?
The chemical change which occurs to an electrolyte when an electric current is passed
What is the difference between metallic and electrolytic conduction?
Metallic:  mobile e- ; unchanged;  Electrolytic conduction:  mobile ions; electrolyte decomposes
What happens to a metal that undergoes discharge?
gains a full outer shell/ becomes stable / becomes an atom
True / False: According to the ECS, a higher metal becomes discharged and a lower metal becomes ionized.
False--higher metal ionizes and the lower metal is discharged
True / False:  A metal will displace a metal that is above it in the ECS from a compound containing the higher metal.
False
True or false: Potassium ionizes the most easily, forms the most stable compound and is the strongest reducing agent.
True
