小中大刚开始做这个实验,请问您们用的是这个亚硫酸氢钠吗?要加水后反应生成亚硫酸氢钠?下面是说明:
S9000
Sigma-Aldrich Sodium bisulfite ReagentPlus®, ≥99%
As a solid, this product is sodium metabisulfite,.
When dissolved in water, it yields sodium
bisufite NaHSO3.
Na2S2O5 + H2O ® 2 NaHSO3
Sodium bisulfite is a reagent that is used in a variety of
large scale applications. These include the removal of
chlorine from bleached fibers in paper manufacture, as
a disinfectant and bleaching agent for wool, the
preparation of hot and cold indigo vats for dyeing, the
coagulation of rubber latex, and the manufacture of
sodium hydrosulfite.
请做过的朋友帮忙看一下,给点意见,谢谢!
