Hint: We have to know that, the electrochemical comparable at times contracted $Eq$ or $Z$, of a substance component is the mass of that component (in grams) shipped by $1$ coulomb of electric charge. What could be compared to a component is estimated with a voltmeter.
Complete answer:
We have to know that, the electrochemical equivalent of a substance is the mass of the substance saved to one of the cathodes when a current of one ampere is passed for one second, for example an amount of power of one coulomb is passed.
We have to know that copper is a substance component with the symbol $Cu$ and nuclear number $29$. It is a delicate, moldable, and bendable metal with high warm and electrical conductivity.
The equation for discovering electrochemical comparable is as per the following:
$Z = \dfrac{M}{q}$
Where,
$M$ = The mass of the substance,
$q$ = the charge passed.
Since,
$q = It$
Where,
$I$ = the current applied,
$t$ = time,
We likewise have,
$Z = \dfrac{M}{{It}}$
If,
$q = 1$coulomb’s
$I = 1$ampere
$t = 1$second.
By using the following expression,
${\text{Electrochemical equivalent = }}\dfrac{{{\text{Equivalent mass}}}}{F} = Z$
Here, the equivalent mass of copper has to be first calculated,
$Equivalent{\text{ mass of copper = }}\dfrac{{Molarmass}}{{valency}}$
Where, the molar mass of copper $M$ is $63.5$ and the valency is two.
$\dfrac{{Molar Mass}}{{valency}} = \dfrac{M}{2} = \dfrac{{63.5}}{2}$
Then,
$F = 96500$
Applying all the values in the electrochemical equation,
$Z = \dfrac{{63.5}}{{2 \times 96500}}$
Hence, option (B) is correct.
Note:
We have to know that a newly uncovered surface of unadulterated copper has a pinkish-orange tone. Copper is utilized as a conveyor of warmth and power, as a structure material, and as a constituent of different metal combinations, like authentic silver utilized in gems, cupronickel used to make marine equipment and coins, and constantan utilized in strain checks and thermocouples for temperature estimation.
