The negative Zn pole of Daniell cell, sending a constant current through a circuit, decreases in mass by `0.13` g in 30 minutes. If the chemical equivalent of Zn and Cu are `32.5` and `31.5` respectively, the increase in the mass of the positive Cu pole in this time is

The negative Zn pole of a Daniell cell, sending a constant current through a circuit, decreases in mass by 0.13 g in 30 minutes. If the electeochemical equivalent of Zn and Cu are 32.5 and 31.5 respectively, the increase in the mass of the positive. Cu pole in this time is

A current of 9.65 A is drawn from a Daniell cell for exactly one hour. If molar masses of Cu and Zn are 63.5 g mol^(-1) and 65.4 g mol^(-1) , respectively, the loss in mass at anode and gain in mass at cathode respectively are

In a Cu-voltameter, mass deposited in 30s is 'm' g. If the time -current graph is shown in the following figure : What is the electrochemical equivalent of Cu ?

In a Cu-voltameter, mass deposited in 30s is 'm' g. If the time -current graph is shown in the following figure : What is the electrochemical equivalent of Cu ?

0.2864 g of Cu was deposited on passage of a current of 0.5 ampere for 30 minutes through a copper sulphate solution. The electrochemical equivalent of copper is

A current of 0.5 A flowing for 30 min deposits 0.2964g of a metal at the cathode. Calculate the equivalent mass of the metal.

An external current source giving a current of 5.0A was joined with Daniel cell arrangement opposing the normal current flow and was removed after 10 hrs. Before passing the current the LHE and RHE contained 1L each of 1M Zn^(2+) and Cu^(2+) respectively. Find the EMF supplied by the Daniel cell after removal of teh external curretn source, E^(@) of Zn^(2+)//Zn and Cu^(2+)//Cu at 25^(@)C is -0.76 and +0.34V respectively.
