Batteries are charged and discharged due to the concentration of the solutions inside. Calculate the voltage of a battery made from zinc in a 0.5M solution of Zn²⁺ and a metal X in a 1 M X²⁺ solution using the table of reduction potentials and Eq. 6 at 25 degrees C. Answer with the unit V, to two decimal places. The standard reduction potential of X is -0.19 volts.Your Answer:[Input Box][Input Box]

From standard sources we can find:- Zn2+ +2e- → Zn = -0.76V According to the problem:- X2+ +2e- → X = -0.19V Now, as the reduction potential of X is higher than that of Zn, so it will get reduced and Zn will get oxidized. Eocell = Eored - Eooxi Eocell = -0.19V -(-0.76) = 0.57V So, the balanced equation will be:- X2+ + Zn → Zn2+ + XNow, Ecell = Eocell -(0.0592÷n)x log([Product]÷[reactant]) Ecell = 0.57 - (0.0592÷2) x log([0.5]÷[1]) = 0.57 - 0.0296 x (-0.3010) = 0.5789V The voltage of the battery will be 0.5789V
