The acqueous solution to determine the equilibrium constant

Reference no: EM13226599

A reaction mixture of 4ml of 2x10^-3 M SCN and 5ml of 2x10^-3 M Fe+3 is diluted to 10ml with 0.1M HNO3 to form the blood-red FeNCS+2 complex. The equilibrium molar concentration of the FENCS+2 determined from a calibration curve is 1.5x10^-4 mol/L. Calculate, in sequence each of the following quantities in the acqueous solution to determine the equilibrium constant for the reaction: a) mole of FeNCS+2 the form in the reacting equilibrium, b) moles of Fe+3 that react to form the FeNCS+2 at equilibrium, c) moles of SCN- that react to form the FeNCS+2 at equilibrium, Kc=[FeNCS+2]/[Fe+3][SCN-]
