Suppose a current of is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for s
WARRIOR [948]

The given question is incomplete. The complete question is:

Suppose a current of 0.920 A is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 47.0 seconds. Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell.

Answer:   0.0484 g

Explanation:

Q=I\times t

where Q= quantity of electricity in coloumbs

I = current in amperes = 0.920 A

t= time in seconds = 47.0 sec

Q=0.920A\times 47.0s=43.24C

AgNO_3\rightarrow Ag^++NO_3^-

Ag^++e^-\rightarrow Ag

96500 Coloumb of electricity electrolyzes 1 mole of Ag

43.24 C of electricity deposits =\frac{1}{96500}\times 43.24=0.00045moles of Ag

\text{ mass of Ag}={\text{no of moles}\times {\text{Molar mass}}=0.00045mol\times 108g=0.0484g

Thus the mass of pure silver deposited on a metal object made into the cathode of the cell is 0.0484 g
