1.	An aqueous solution containing one mole per litre of Cu(NO_3)_2 , AgNO_(3),Hg(NO_3)_2 and Mg(NO_3)_2 is being electrolysed using inert electrodes. The values of the standard electrode potentials in volts (reduction potientials) are Ag \|Ag^(+) = +0.80,2Hg\|Hg^(2+)=0.79 Cu\|Cu^(2+) = + 0.34, Mg\|Mg^(2+) =-2.37 With increasing voltage, the sequence of deposition of metals on cathode will be
Answer» Ag,HG,Cu,Mg Mg,Cu,Hg,Ag Ag,Hg,Cu Cu,Hg,Ag Solution :`rho = R.(a)/(l) = (25 xx 3.2)/(1.6) =50 ` ohm cm `K = (1)/(rho) = (1)/(50) =0.02 S cm^(-1)` `Lambda_(eq) = K xx V = K xx (1000)/("Normality")= (0.02 xx 1000)/(0.5)` `=40 s cm^2 ` EQUIV.
