1.0 M acid and two pt electrodes connected to a voltmeter. You then add 10.00 ml of 1.00 M Fe^+2 solution to the beaker. The temperature of the solution is maintained at 25 C.(R= 8.314 coulomb V/(mol K), F= 9.64853 x 10^4 coulomb/mol)
A) Write the standard half-cell reduction reaction equation for reactive species in the beaker.
B) Determine the cell potential(Ecell) at the moment of mixing.
C) Determine the equilibrium constant(Keq) for the reaction system.
D) if enough of the 1.00 M Fe^+2 solution is added to reach the equivalence point, determine the new cell potential.
E) Determine the cell potential(Ecell) if 20.0 ml of 1.00 M Fe^+2 solution is added to the solution.
Determine the % relative error for the following quantities: if there is no uncertainty given for a specific value, assume an absolute error of "1" in the last digit.
