韦氏试剂标准溶液

作用：韦氏试剂（Wijs）是碘值侧定方法中使用的特殊试剂。

Wijs solution is a solution of containing iodochloride in glacial acetic acid. It is used as a mixture to test material (fats, oils or emulsions) for idodine value or iodine number or the ability of material to absorb iodine. often this is calculated by running a blank and a sample with same amount of wijs solution and doing a back titration often with sodium thiosulfate with known normality or molarity. question for others if iodobromide in glacial acetic acid is also known as wijs solution since that is the material i used most often to test iodine value.
