Empty the content into a beaker. Obtain 10ml of 5.00x10 - 4 M KSCN solution in a small beaker then pipette 10ml of 0.150M Fe(NO3)3 and 5.00ml of 5.00x10 -4M KSCN into 25 ml volumetric flask dilute to the mark with 0.1 M HNO3 calculate concentration of Fe3+ and SCN in solution taking dilution into account. One reactant is limiting and one is excess determine [FeSCN2+] and determine the complex concentration. Calculate all the equilibrium [FeSCN2+] in the various temperature you measured after determining initial concentration of Fe and SCN determine in equilibrium and calculate K in each Part A absorbance 0.358 Part B absorbance 0.557 absorbance different temperature 0.546 0.562 0.592 0.625
