TRIAL 1
[Fe+3] = Initial concentration of Fe(NO3)3 * Volume of the Fe(NO3)3 solution/ Total volume = 0.0020 M * 5 / 10 = 0.001 (M)
[SCN-] = Initial concentration of KSCN * Volume of the KSCN solution/ Total volume = 0.0020 M * 2/ 10 = 0.0004 (M)
TRIAL 2
[Fe+3] = 0.0020 M * 5 / 10 = 0.001 (M)
[SCN-] = 0.0020 M *3 / 10 = 0.0006 (M)
TRIAL 3
[Fe+3] = 0.0020 M * 5 / 10 = 0.001 (M)
[SCN-] = 0.0020 M *4 / 10 = 0.0008 (M)
TRIAL 4
[Fe+3] = 0.20 M * 9 / 10 = 0.18 (M)
SCN-] = 0.0020 M *1 / 10 = 0.0002 (M)

2. In Part A of this experiment, you prepare five FeSCN solutions (one that is just a blank) according to the reaction below Fe (aq) SCN (aq) > FeSCN (a) SCN formed We assume that the starting SCN determines the concentration of Fe (because Fe is in excess and SCN is limiting). Calculate the concentration ot FeSCN2 that forms for each of the solutions (Beakers 1-4) and fill out the table below. Show your calculations beneath the table. Concentration of...
