the solubility of slightly soluble ionic compound is measured, the product the substance can be calculated (Ebhing Gal Etampl 17.3. This is the method that you will adopt for Ca in this experiment. The equilibrium between solid Caio, and its ioes in a salaurated solution is If some analytical technique is used lo ine concentratimn of eitherca ions or losions in the determi saturated solution, the solubility of Calob will be known, and the solubility product constant (Ke) n be calculated. this experiment, you will determine the concentration of los ons through a titration with a standardized solution of Na S O, (sodium thiosulfate) in the presence of K (potassium iodide). using starch as an indicator. A definition of standardization can be found in the experiment "An Acid-Base Titration Curve Potassium iodide will react with the iodate ions lo give l:as the sole product containing iodine. The reaction is The molecular iodine reacts with S O ions during the titration according to 21 (ag) t Sloe (ay) where so is the tetrathionate ion, when these two equations are combined, multiplying the second eaction by 3 so the intemediate l is eliminated, the net reaction occurring in the titration is
