  • T/F While using reference electrodes, the internal liquid level should always be kept above that of the sample solution.
    False
    True
  • Why is Standard hydrogen electrode called as the primary reference electrode?
    ts output potential is dependent on the composition of the s
    It must have a known output potential
    It is employed in conjunction with the indicator or working
    It must have a constant output potential
  • T/F If hydrogen electrode acts as cathode, hydrogen is reduced.
    False
    True
  • In Hydrogen electrode, the electrode is placed in a solution of ____ M HCl.
    0.5
    1
    2
    Saturated
  • Why is Standard hydrogen electrode called as the primary reference electrode?
    it has a known output potential
    Its output potential is independent of sol'n composition
    Its output potential is zero volts
    It has a constant output potential
  • Which of the following is not the disadvantage of standard hydrogen electrode primary reference electrode?
    Presence of oxidising agents alters the potential
    H2 gas at 1 atmospheric pressure is difficult to set up and
    It gives salt error
    Platinum can be easily poisoned

    False
    True
  • Proper care of pH electrodes includes
    Store the electrode in a solution of 4 M KCl
    Don't store in distilled or DI water - ions leach out
    All of the above
