In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.

Describe the role of SiO_2 in the extraction of Copper from Copper matte.

One half-cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknonw concentration. It other half cell consists of a zinc electrode dipping in 1.0M solution of Zn(NO_3)_2 . A voltage of 1.48V is measure for this cell. Use this information to calculate the concentration of silver nitrate solution used (E_(Zn^(2+)//Zn)^0=-0.76V,E_(Ag^+//Ag)^0=+0.80V)

A copper silver cell is set up. The copper ion concentration is 0.10M . The concentration of silver ion is not known. The cell potential when measured was 0.422V. Determine the concentration of silver ions in the cell. (Given) E_(Ag^(2+)//Ag)^@=+0.80V,E_(Cu^(2+)//Cu)^@=+0.34V

Two electrolytic cell containing AgNO_3 solution and dilute H_2SO_4 solution were connected in series. A steady current of 2.5 ampre was passed through them till 1.078g of silver was deposited. (Ag = 108 u, IF = 96500 C). How much electricity was consumed?

Two electrolytic cell containing AgNO_3 solution and dilute H_2SO_4 solution were connected in series. A steady current of 2.5 ampere was passed through them till 1.078g of silver was deposited. (Ag = 108 u, IF = 96500 C). What was the weight of oxygen gas liberated?

Three electolytic cells A,B,C containing solutions of ZnSO_4 , AgNO_3 and CuSO_4 respectively are connected in series.
