A solution containing 100.0 mL of 0.155 M EDTA buffered to pH 10.00 was titrated with 100.0 mL of 0.0152 M Hg(ClO4)2 in a cell:
calomel electrode (saturated)//titration solution/Hg(l)
Given the formation constant of Hg(EDTA)2-, logKf= 21.5, and alphaY4-=0.30, find out the cell voltage E.
Hg2+(aq) + 2e- = Hg(l) E0= 0.852 V
E' (calomel electrode, saturated KCl) = 0.241 V
From the following reduction potentials
I2 (s) + 2e- = 2I- (aq) E0= 0.535 V
I2 (aq) + 2e- = 2I- (aq) E0= 0.620 V
I3- (aq) + 2e- = 3I- (aq) E0= 0.535 V
a) Calculate the equilibrium constant for I2 (aq) + I- (aq) = I3- (aq).
b) Calculate the equilibrium constant for I2 (s) + I- (aq) = I3- (aq).
c) Calculate the solubility of I2 (s) in water.
2. (3 pts) Consider the unit cell for the spinel compound,
CrFe204. How many total particles are in the unit cell?
Also, show how the number of particles and their
positions are consistent with the CrFe204
stoichiometry - this may or may not be reflected by the
particle colors in the diagram. (HINT: In the diagram,
the blue particle is in an interior position while each red
particle is either in a corner or face position.)
