The permanganate was quickly decolorised and the cyclohexene layer remained floating on the water layer. KMnO4 is an oxidising agent. Secondly, not all redox reactions are instantaneous. PartIn acidic medium ie. Add an excess of concentrated H2SO4. Oxidation Edit. To determine the effect of a catalyst on the rate of reaction. Reaction with Bromine and Potassium Permanganate and Unknown If "No Reaction" occurs write "NR" in the box. The aim of this work is to study effect of two powerful oxidants (potassium permanganate and chlorine) on natural organic matter in surface waters. Other products are HCl & SO 2, HCl & POCl 3 and H 3 PO 3 respectively. (7 marks) Explain why certain alcohols reacted in KMnO4 (aq) and others didn’t. Na2C2O4(s)+ KMnO4---> NaMnO4 +KC2O4 i know what i did is wrong i am confused how Na and C and O4 be with each other i dont understand too Na2C2O4(s) how did Na got 2 and C got 2 and O 4 -----> how did they do it. Sufficient contact time must be provided to exhaust the permanganate residual before reaching the distribution system. It is, however, capable of further oxidizing the glycol with cleavage of the carbon-carbon bond, so careful control of the reaction conditions is necessary. Basic solution Potassium permanganate, KMnO4, is a powerful oxidizing agent. Some other common uses of potassium permanganate include industrial, biomedical and as a disinfectant.
