Why is Standard hydrogen electrode called as the primary reference electrode?
It must have a known output potential
ts output potential is dependent on the composition of the s
It is employed in conjunction with the indicator or working
It must have a constant output potential
Why is Standard hydrogen electrode called as the primary reference electrode?
it has a known output potential
Its output potential is zero volts
Its output potential is independent of sol'n composition
It has a constant output potential
Which of the following is not the disadvantage of standard hydrogen electrode primary reference electrode?
H2 gas at 1 atmospheric pressure is difficult to set up and
