Question

metal that is not deposited at cathode when its aqueous solution is electrolysed​

Answer 1

Answer:

A solution containing one mole per liter of each Cu(NO3)2, AgNO3, Hg2(NO3)2 and Mg(NO3)2 is being electrolysed by using inert electrodes. The values of standard electrode potentials in volts (reduction potentials) are:

Ag+/Ag=+0.80,

Hg22+/Hg=+0.79,

Cu2+/Cu=+0.34,

Mg2+/Mg=−2.37

Explanation:

hop that helped.
