acidify 即系提供酸性环境令MnO4-作为oxidizing agent的反应可以发生： MnO4- + 8H+ + 5e- => Mn2+ + 4H2O (明显这个反应需要H+才可以发生) KMnO4 可以用 dilute H2SO4 去 acidify，因为两者并无reaction，即系H2SO4真正只提供acidic medium 如果用HCl，会与MnO4- react，咁就会消耗左MnO4-，...
The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. 2MnO4-(aq)+16H+(aq)+10Cl-(aq)=2Mn2+(aq)+5Cl2(g)+8H2O(l) ...

2MnO4-+ 16H++ 5C2O42-→ 2Mn2++ 8H2O + 10CO2 Another potentially important fact, is that the currently observed reaction occurs at room temp (~23C), and the wanted reaction would probably need a higher temp to start (both reactants are negatively charged). Thanks for the replies. S...
Re: In a mixture of plant matter, what can I expect to react with KMnO4 and H2SO4? « Reply #2 on: June 07, 2019, 01:51:09 PM » You should be able to crystallize out the oxalate under strong acid conditions. Try the method described in this review:Oxalate in crop plantsJ....
We use sulphuric acid in this titration with KMnO4. The solution which contains MnO4- ion in it is purple in color. While the solution containing Mn+2ions is colorless. Thus, potassium permanganate when reacts with a reducing agent it works as a self-indicator also. ...
What are the names of the products when these isomers react with excess KMnO4? What alkene can be used to prepare the following alcohol as the exclusive product of a two-step hydroboration-oxidation sequence? What alkene can be used to prepare the follow...
