WebSulfuric acid is the titrant used routinely by the U.S. Geological Sur-vey (USGS). The normality of sulfuric acid titrant is subject to change with time; proper storage and standardization of the acid titrant are essential. Reagents should be stored in a cool (less than 25-30 ° Celsius (°C)), dry, dark place to ensure maximum shelf life. Webnormal concentration of iodine titrant (N I) for each portion of standard titrated, as follows: N I = N S × 5 ÷ V N I = Normality of the iodine titrant (certified or standardized value) N S = Normality of the standard thiosulfate solution V I = Volume of iodine titrant used at the endpoint of the titration (mL) Use the average N I
