The equilibrium constant for I2(ag)+ I- (ag)=>I3- (aq) may also be found by measuring two solubilities. The solubility of I2 (s) in .100 M NaN03 solution at 25 degrees celcius , where no complexes are formed, is .00131 moles per liter. The solubility of I2 (s) in .100 M KI solution at 25 degrees celcius is .05135 moles per liter. The .1 M NaN03 provides the same ionic environment as .1 M KI. From this information calculate the concentration of I3-, I-, I2 in the latter solution and then calculate K1.
