WebSince iodometric titrations are widely used in many senior courses, ascorbic acid can be used as a weighable standard when the experimental procedure involves the standardization of an iodine solution. Conclusion The standardization of an iodine solution using ascorbic acid as the weighable standard was shown to be accu rate and precise. WebSince iodine is involved, and these are redox reactions not neutralization reactions, these titrations are called iodometric titrations. However, in kinetics lab experiments, this reaction is often used as an example where the speed of a …
