Permanganates, MnO

Balance the equation for the reaction between permanganate, MnO faqj, and plutonium(III), Pu+Yagj, to form manganous, Mn+2(ag), and plutonyl ion, PuO faq), in acid solution. 

We know that lppm = lmgl 1 therefore a = 0.743lcm-1 mg-1 inserting 10-3 for the prefix m results in a — 7431cm-1 g-1. To convert a into s we divide the mass by the molar mass of permanganate (MnO = 118.93 gmol-1) to get e — 88,3631mol-1 cm-1. 

Complex oxides are normally found when a nonmetal is present, with oxoanions such as nitrate NO.v, carbonate -0 a > phosphate or sulfate SOj, but are also sometimes formed by metals in high oxidation states (e g. permanganate MnO jn KMnOA When a compound contains two... 

Equations for redox reactions, such as the oxidation of magnesium metal by chlorine gas discussed at the beginning of this section, are relatively straightforward to balance. In the laboratory, however, we often encounter more complex redox reactions involving oxoanions such as chromate (Cr04 ), dichromate (Cr207 ), permanganate (MnO ),...
