Question

SECTION -A (OBJECTIVE TYPE)
O(I). Read the passage given below and answer the following questions:
The potential of individual hall cell cannot be measure. We can measure only the
difference between the two bull cells polentials that give the EMF of the cell. If we
arbitrarily choose the potential of ond electrode (half-cell), then and that of the
other can be determine with respect to this. Ir the concentration of the , oxidized
and the reduced forms of the mpecies in the right hand half cellare Unity then the
cell potential is equal to standard electrode potential
(a) How is the standard hydrogen electrode represented?
(b) What does She consist of
(c) Sometime metals like Platinum or Gold are use as inert electrode. Give reason
(d) Which element has the highest standard electrode potential?​

Answer 1

Answer:

1*The standard hydrogen electrode consists of a platinum electrode coated with platinum black. The electrode is dipped in an acidic solution and pure hydrogen gas is bubbled through it.

2*BECAUSE THEY ARE CHEMICALLY UNNRACTIVE
