A pin of 2 cm length and 0.4 cm diameter was placed in AgNO_(3) solution through which a 0.2 ampere current was passed for 10 minute to deposit silver on the pin. The pin was used by a surgeon in lachrymal duct operation. The density of silver and electrochemical equivalent are 1.05 xx 10^(4) kg m^(-1) and 1.118 xx 10^(-6) kg//"coulomb" respectively. What is the thickness of silver deposited on the pin? Assume that the tip of the pin contains negligible mass of silver.

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.

The most pupular electrochemical cell, daniel cell was originally developed by the English chemist john F daniel the general assembly of the cell is as given below An undergraduate student made a Daniel cell using 100cm^(3) of 0.100MCuSO_(4) ad 0.100M ZnSO_(4) solution respectively. The two compartments are connected by suitable salt bridge. [given E_((Cu^(2+)//Cu))^(@)=0.34V,E_((Zn^(2+)//Zn))=-0.76V,(2.30RT)/(F)=0.06,log2=0.3] Q. A labmate of the student asked her for some solid CuCl_(2) . while she was lifting the bottle from a shelf, the lid of the bottle slipped and some amount of CuCl_(2) fell in the CuSO_(4) compartment at constant volume. She measured the emf of the cell again and found that it has increase by 9 mV. She used this data to calculate the amount of CuCl_(2) that had spilled in the compartment. Calculate the mass of CuCl_(2) that had spilled into the daniel cell? (molar mass of CuCl_(2)=135(g)/(mol))
