Reduction potentials of A,B,C and D are 0.8 V 0.79 V, 0.34 V and -2.37 V respectively which element displaces all the other three elements
Evaluate the following : (i) i^(7) (ii) i^(51) (iii) (1)/(i) (iv) i^(-71) (v) (i^(37)+(1)/(i^(67)))
Given that E^o values of Ag^+//Ag, K^+//K, Mg^(2+)//Mg and Cr^(3+) //Cr are 0.08 V, -2 .93 V, -2 37 V and -0. 74 V respectively. Therefore the order for the reducing power of the metal is .
The standard reduction potentials of Cu^(=2),Ag^(+),Hg^(+2) and Mg^(+2) are 0.34v,+0.80v,+0.79V and -2.37V respectively. With increasing voltage, the squence of deposition of metals on the cathode from a molten mixture containing all those ions is
