The correct order of electro chemical equivalent (e) of Sodium, Magnesium and Aluminium is
View answer and explanation
Correct option: A
Na > Mg > Al
Option A is correct because the electrochemical equivalent (e) is directly proportional to the molar mass and inversely proportional to the number of electrons involved in the half-cell reaction. For Na, Mg, and Al, the molar masses are approximately 23, 24, and 27 g/mol, and the number of electrons involved are 1, 2, and 3, respectively. Therefore, the order of electrochemical equivalents is Na > Mg > Al.
