Answer: Mass of silver deposited at the cathode is 37.1g
Explanation: According to Faraday Law of Electrolysis, the mass of substance deposited at the electrode (cathode or anode) is directly proportional to quantity of electricity passed through the electrolyte
Faraday has found that to liberate one gm eq. of substance from an electrolyte, 96500C of electricity is required.
+e− ==> Ag(s)
Given that
Current (I) = 8.5A
Time (t) = 65 *60 = 3900s
Quantity of electricity passed = 8.5*3900 =33150C
Molar mass of Ag= 108g
96500C will liberate 108g
33150C will liberate Xg
Xg= (108*33150)/96500
=37.1g
Therefore the mass of Ag deposited at the cathode is 37.1g.
All the given species have the same charge except peroxide.
<h3>Charges on ions</h3>- The charge on monohydrogen phosphate is negative because of its formula,
.
- The charge on permanganate is negative. The formula is
- The charge of oxide (
) is negative.
- The charge on peroxide is ( R−O−O−R) is neutral.
- The charge on oxalate,
, is negative.
Thus, only peroxide is unique.
