检测食盐中碘元素的方法若要简单易行并直观,通常的思维是使食盐中的碘元素转化为单质碘,再让碘使淀粉变蓝。具体有两种较严密的方法检测碘元素。方法一:如果让食盐中的部分KIO_3分解变成KI,在酸性条件下被另一部分KIO_3氧化,再用淀粉来检验,检测结果的可信度就高多了:把加碘食盐分成两等份,将 To detect salt iodine in the method to be simple and intuitive, the usual idea is to salt iodine into elemental iodine, let iodine blue turn starch. There are two more specific methods to detect iodine. Method One: If KIO_3 in the salt is decomposed into KI, oxidized by KIO_3 under acidic conditions and then tested with starch, the test results are much more credible: the iodized salt is divided into two equal parts ,will
