(a) Arrrange A,B,C and D in order of incresing electrode potential in the electrochemical series if (i) A+B^(+)rarrA^(+)+B,(ii) B +D^(+) rarr B^(+)+D (iii) B+C^(+)rarrB^(+)+C,(iv) C^(+)+Drarr NO reaction (b) on the basisof the above data predict which of the following reaction will ocur (i) A+C^(+) rarrA^(+)+C, (ii) A^(+)+D rarrA+D^(+)
Answer» Solution :(a) In the electrochemical SERIES the atoms or species arearranged in ORDER of their decreasing electrode potential (i) since B is reduced by A therefore B has higher electrode potential than A (ii) since D is reduced by B therefore D has higher electrode potential than B (iii) Since C is reduced by B therefore C has higher electrode potential than B (iv) since there is not reaction between `C^(+)` and D i.e C is not reduced by D therefore elecrode potential of the four ELEMENTS decrease in the order `D gt C gt B gt A` (b) (i) since electrode potential of C is higher than that of A therefore `C^(+)` can be easily reduced by A reacton (i) will occur (ii) since electrode potential of D is higher than that of A therefore `A^(+)` cannot be reduced of by D i.e reaction (ii) wil not occur
