Question

(NONE) The electrochemical equivalent $(Z)$ is defined by the relation $w = Z \cdot I \cdot t$,where $w$ is the mass in grams,$I$ is current in Ampere

Vedclass · Accepted Answer

The units of electrochemical equivalent are $g/Coulomb$

Vedclass · Answer

(NONE) The electrochemical equivalent $(Z)$ is defined by the relation $w = Z \cdot I \cdot t$,where $w$ is the mass in grams,$I$ is current in Amperes,and $t$ is time in seconds. Since $1 \ Coulomb = 1 \ Ampere \cdot 1 \ second$,the unit of $Z$ is $g/Coulomb$. All statements $A$,$B$,$C$,and $D$ are scientifically correct. However,if this is a multiple-choice question where one must be incorrect,there might be a context-specific error. Given the standard definitions: $A$ is correct as $NaCl$ dissociates into ions. $B$ is correct as $Z = w / (I \cdot t)$. $C$ is correct as $n$ is the stoichiometric coefficient of electrons. $D$ is correct by $IUPAC$ convention. Since all are correct,the question is technically flawed.
