Chapter 19, Problem 19.126SP

(a)

Interpretation Introduction

Interpretation:

The total charge consumed for completion of electrolysis has to be calculated.

Concept Introduction:

  • The amount of electrical charge that is passing through a circuit depends upon the amount and time of the flow of current.  The electrical charge is measured in Coulomb.

  Q=It

  Where,

  Q is the charge in Coulomb

  I is the current in Ampere

  t is the time in second

  • Mole is the mass of the substance that is having Avogadro number of particles.  The number of moles of a given substance can be calculated by dividing its weight to molecular weight.
  • Faradays First law of electrolysis says that the quantity of substance deposited on an electrode is proportional to the charge passed through the solution.

    m = Z×Q

    Where,

    m is the amount of substance liberated

    Q is the quantity of charge passed

    Z is the electrochemical equivalence of the substance

  • Ideal gas equation is an equation that is describing the state of a imaginary ideal gas.

    PV=n RT

    Where,

    P is the pressure of the gas

    V is the volume

    n is the number of moles of gas

    R is the universal gas constant (R=0.0821LatmK-1mol-1)

    T is the temperature
