For how much time 10 A current should be passed through the molten NaCl to obtain 36.47 g of sodium metal at cathode? Efficiency of current is 85 % ($ At.wt Na = 23 g mol ^ {(-1)}$)
When 5 L aqueous solution of $ CuSO_4 $ is electrolysed between inert electrodes by passing 25 A current its concentration decreases from 2.0 M to 1.2 M then theoritically for how much time current would have been passed ?
What is the correct order of specific conductance of given metals?
When 10 L aqueous solution of $ CuSO_4 $ is electrolysed between inert electrodes by passing electric current for 20 hours its concentration decreases from 0.7 M to 0.2 M then how much electric current would have been passed ?
On the basis of given data match the convounds of group 1 with values of molar

A Sulphur containing species that cannot be a reducing agent is
If at constant temperature specific conductance of aqueous solution of KCI is $ x mho. (cm) ^{-1} and on measuring its resistance it is found to be y \Omega . with the same instrument if resistance of aqueous solution of NaCl is found to be z \Omega then what will be its specific conductance?
Using 2 g Hg cathode Cd—Hg amalgam is obtained by electrolysis Of $ CdCl_2 $ then how much ampere electric current should be passed for 1000 seconds to obtain Cd-Hg having Cd? ($ At.wt Cd = 112.5 g mol ^ {-1} $ )
According to Faraday's law of electrolysis, the amount of substance deposited at an electrode is directly proportional to the quantity of electricity passed. To deposit 2 g of Cd (112.5 g/mol), the required current is 13.72 A for 1000 seconds.
$ A_m - A_m ^ \circ - A.C ^ {1 \over 2 } $ is related to which compound?
$ A_m - A_m ^ \circ - A.C ^ {1 \over 2 } $ is not related to which compound?
