Hint: The electrochemical equivalent, sometimes abbreviated \[Eq\] or \[Z\], of a chemical element is the mass of that element (in grams) transported by 1Coulomb of electric charge. The electrochemical equivalent of an element is measured with a voltmeter.
the weight of a substance (such as an element) deposited or evolved during electrolysis by the passage of a specified quantity of electricity and usually expressed in gram per Coulomb, the value for silver as the usual standard being \[0.001118 gram\].
Complete step by step answer:Electrochemical equivalent is the mass deposited in electrolysis by passage of 1 Coulomb of charge.
The electrochemical equivalent of a substance may be defined as the mass of the substance deposited to one of the electrodes when a current of 1 Ampere is passed for 1 second, i.e. a quantity of electricity of 1 Coulomb is passed.
The formula for finding electrochemical equivalent is as follows:
\[Z = \dfrac{M}{q}\]
where, '\[M\]' is the mass of substance and
'\[q\]' is the charge passed.
Hence, its S.I. unit is gram per Coulomb
Also \[q = it\]
Hence, \[Z = \dfrac{M}{{it}}\]
where ' \[i\]' is the current applied and
'\[t\]' is the time.
Hence, the correct option is B.
Note:Electrochemical equivalent is totally differ from chemical equivalent. Electro-chemical equivalent is the ratio between chemical equivalent weight and the Faraday number it's representation formula is Electrochemical equivalent \[ = \dfrac{E}{F}\]. It is that mass of the substance due to passage of deposited or removed by the process of electrolysis. Electrochemical equivalent: Electrochemical equivalent on the other hand, refers to the mass of substance deposited when a current of 1 Ampere is passed for 1 second during electrolysis. (or the mass of a substance deposited when 1 Coulomb of electricity is passed through).
While the chemical equivalent is the weight of the 1 gram of substance that can combine with or displace with \[1g\] of the hydrogen. Formula \[\dfrac{{weight}}{{valency}}\] is the chemical formula. Chemical equivalent of an element is the value obtained by dividing the atomic weight of the given element by its valency.
