Question

250 mL of a waste solution obtained from the workshop of a goldsmith contains 0.1 M AgNO and 0.1 M AuCl. The solution was electrolyzed at 2 V by passing a current of 1 A for 15 minutes. The metal/metals electrodeposited will be: 3

(A) Silver and gold in proportion to their atomic weights
(B) Silver and gold in equal mass proportion
(C) Only silver
(D) Only gold

Prashant Kotian · Accepted Answer

Correct answer: A) SILVER AND GOLD IN PROPORTION TO THEIR ATOMIC WEIGHTS. As voltage is '2V' so both Ag and Au will reduce and their equal gm equivalent will reduce so gmeq Ag = gmeq of Au So,
