This clock reaction uses sodium, potassium or ammonium persulfate to oxidize iodide ions to iodine. Sodium thiosulfate is used to reduce iodine back to iodide before the iodine can complex with the starch to form the characteristic blue-black color.

A solution of sodium thiosulfate was standardized by dissolving 0.1110 g KIO3 in water, adding a large excess of KI, and acidifying with HCl. The liberated iodine required 40.64 mL of the thiosulfate solution to decolorize the blue starch/iodine complex. Calculate the molar concentration of the Na2S2O3.IO3^- (aq) I^- (aq) ⟶ I2 (s)I2 (s) S2O3^2- (aq) ⟶ I^- (aq) S4O6^2- (aq)MM: KIO3 = 214.00Na2S2O3 = 158.11I2 = 253.81
