A test system and method is described for determining if a material (e.g. uric acid) oxidizable by iodine is present in an aqueous fluid in an amount equal to or greater than a predetermined amount and which includes a dry solid iodine indicator and a dry solid means for rapidly ...
Iodoform Test: (Iodine is one of the reagents used in this test. It is highly toxic and causes burns. Run this test on all of the known and unknown compounds. For each compound you want to test place 2 drops of the compound that you are testing in a separate micro test tube. Add ...

A iodometric method is used. Iodide ions react with iodate ions in the presence of sulfuric acid to form iodine (Step 1).The sulfite present in the water sample then reduces the iodine back to iodide (Step 2). An excess of iodate ions will generate additional iodine, which will form a ...

The endpoint of iodine titrations is conveniently followed with starch indicator, as small amounts of iodine form a dark blue complex with it. (This is also the basis of a qualitative test for the presence of starch in paper.) Titrants or analytes that are highly colored can be used as ...
Iodometric titration to determine the concentration of bromate anions in the electrolysed solution, measured by adding thiosulfate solution to titrate the red iodine (I2) molecules, which evolved by reducing the bromate anions formed in the electrolysis test with potassium iodide (KI), to a colour...
