Three electrolytic cells A,B and C containing electrolyses of zinc sulphate, silver nitrate and copper sulphate respectively were connected in series. A steady current of 1.50 amp was passed through them until 1.45g of silver were deposited at the cathode of cell B.
HOw long did the current flow?

Three conductivity cells A, B and C containing solutions of zinc sulphate, silver nitrate and copper sulphate respectively are connected in series. A steady current of 1.5 amperes is passed through them until 1.45 g of silver is deposited at the cathode of cell B. How long did the current flow ? What mass of copper and what mass of zinc got deposited in their respective cells ? (Atomic mass : Zn = 65.4 u, Ag = 108 u, Cu = 63.5 u)

Two electrolytic cells containing silver nitrate solution and dilute sulphuric acid solution were connected in series. A steady current of 2.5 amp was passed through them till 1.078 g of silver was deposited? [Ag=107.8g mol^-1, 1f=96500C] What was the weight of oxygen gas liberated?

A current of 4 amp was passed for 1.5 hours through a solution of copper sulphate when 3.2 g of copper was deposited. Calculate the current efficiency.

Three electrolytic cells X,Y,Z containing solution of NaCl, AgNO_3 and CuSO_4 respectively are connected in series combination. During electrolysis 21.6gm of silver deposits at cathode in cell Y. Which is incorrect statement.

Aquesous copper sulphate solution and aqueous silver nitrate solution are electroolysed by 1 Ampere current for 10 minutes in separate electrolytic cells. Will the mass of copper and silver deposited on the cathode be same or different? Explain your answer.

Calculate how long it will take to deposit 1.0 g of chromium when a current of 1.25A flows through a solution of chromium sulphate.

In a potentiometer, a standard cell of emf 5V and of negligible resistance maintains a steady current through the galvanometer wire of length 5 m. Two primary cells of emfs epsilon_(1) and epsilon_(2) are joined in series with (i) same polarity and (ii) apposite polarity.The combination is connected through it galvanometer and a joined to the potentiometer. The balancing length is the two cases are found to be 350 cm and 50 cm respectively Find the value of emfs of the two cells
