- Manganate Ion (MnO4²⁻): - Let the oxidation state of Mn be x. - The equation is: x+4(−2)=−2 - This simplifies to: x−8=−2 - Therefore, x=+6. - Permanganate Ion (MnO4⁻): - Let the oxidation state of Mn be x. - The equation is: x+4(−2)=−...
The optimum reaction conditions were defined, a new method of determining iodine ion by pormanganatefading spectrophotometrywas set up. 在稀硫酸介质中,碘离子能快速、定量地还原高锰酸根,在加入碘离子前后,高锰酸钾溶液在波长525nm处的吸光度发生显著变化,且吸光度之差△A与加入的碘离子的浓度成正比,确定了...
