Dissolved Oxygen Test Kit

Procedure: Small amount of sample is collected in a test tube and an indicator reagent is added to the sample. Use the dropper bottle, the titrant, until the color changes. To calculate the concentration just multiply the number of drops required by the titrant by a simple factor given in the test kit manual.

The dissolved oxygen in the sample oxidizes manganous hydroxide to manganic hydroxide which, in turn, oxidizes iodide to free iodine in an acid medium. The iodine liberated is determined by drop count titration.
