A student is calculating the concentration of her standard solutions in order to create the calibration curve (standard curve). Calculate the equilibrium isothiocyanatoiron(III) ion concentration, [FeNCS2+]eq, for a solution created by combining 2.00 mL of 0.183 M Fe³+ (aq) with 225μL of 0.00199 MSCN- (aq). Give your answer to three decimal places. Also give your answer in millimolar (mM) (because you won't be able to enter an answer in scientific notation here). You may assume that the volumes of these dilute, aqueous solutions are additive.

Potentiometric Titrations

Potentiometric titration is one of the important titration methods and is mainly carried out to characterize acid solutions. It follows a method similar to that of the normal titration technique, but the main difference is that there is no indicator used in the potentiometric titrations. Instead of using an indicator, electrodes are employed for monitoring the whole titration process. A scientist named Robert Behrend did the potentiometric titration for the first time, and it was done using the mercurous solution and potassium chloride.
