Azide Modification (Winkler Titrations) was used to experimentally determine concentrations of DO, following Standard Methods 45000 C. Azide modifications are used for most ,wastewater,, effluent, and stream samples, especially if samples contain more than 50 pg NO2-NL and not more than 1 mg ferrous iron/L. Sodium thiosulfate was used as a titrant, and potassium biiodate as a standard which helped to determine the exact concentration of our titrant.In the fourth laboratory ,experiment, ...
