Consider the following Galvanic cell:- By what value the cell voltage when concentration of ions in anodic and cathodic compartments both increased by factor of 10 at 298K:
What type of a battery is lead storage battery? Write the anode and cathode reactions and the overall cell reaction occurring in the operation of a lead storage battery. (b) Calucluate the potential for half-cell containing. 0.10 M K_(2)Cr_(2)O_(7)(aq), 0.20 M Cr^(3+) (aq) and 1.0 xx 10^(-4) M H^(+) (aq) The half -cell reaction is Cr_(2)O_(7)^(2-) (aq) + 4H^(+) (aq) + 6 e^(-) to 2 Cr^(3+) (aq) + 7H_(2)O(l) and the standard electron potential is given as E^(o) = 1.33V .
In a concentration cell, Zn|Zn^(2+) (0.1M) || Zn^(2+) (0.15M) | Zn , as the cell discharges:
Two concentration cells of Ag with Ag electrode in AgNO_(3) in first cell concentration of one electrode is 1M and other electrode is 0.1 M and emf is 0.065 V in second cell concentration of one electrode is 1 M and other electrode is 0.01 M calculate the emf of second cell
