title: Statistical evaluation of the N-bromosuccinimide and Iodine as titrimetric methods for estimation of vitamin C in orange juice and pharmaceutical preparations.
abstract: N-bromosuccinimide (NBS) and Iodine solution have been used separately for oxidation of vitamin C in orange juice and pharmaceutical preparations. The quantitative results obtained by the two methods have been statistically evaluated for evidence of systematic difference, if any, between the two methods. The t-test has shown that titration with dilute solution (0.0022 M) of NBS has produced better results as compared to Iodine method. On the contrary a concentrated Iodine solution (0.0828 N) gave good results.
