The HI3850-100 are reagents for the determination of ascorbic acid by iodometric titration with the HI3850 ascorbic acid chemical test kit. There are enough reagents for approximately 100 tests to be used with Hanna’s test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each bottle for traceability.
For determination of ascorbic acid, a reaction in acidic solution occurs with the ascorbic acid in the sample reacting with a potassium iodate reagent. The reaction generates triiodide that is converted to iodide ions while ascorbic acid is present, when all ascorbic acid has been consumed the triiodide produced reacts with the starch indicator creating a blue-black color. The number of drops of reagent used to achieve this color can be multiplied by 10 to give a concentration of ascorbic acid in mg/L. These reagents are designed to be used with samples that have an expected ascorbic acid range of 10 to 200 mg/L ascorbic acid.
