Question 44

Conduction through Liquids and Gases

In Faraday's law of electrolysis, a graph of mass deposited against the quantity of electricity is plotted. The slope of the graph gives

  1. A.the electrochemical equivalent.
  2. B.the charge released.
  3. C.the current flowing.
  4. D.the energy released.
Show the answer and explanation

Answer: A (the electrochemical equivalent.)

Explanation

Faraday's first law: m = zQ. A graph of m against Q is a straight line of slope z, the electrochemical equivalent.
