Due to poor eye-sight and non vertical readings reading might be incorrect. the reaction shows that for 2 moles of KMnO4 or MnCl2 you need 16 moles of HCl . Donc 124, 847g de KMnO4 en solution acidifiée réagiront avec 138,339g de H2O2 à 33% pour donner 0.79 mole de O2. Je ne comprends pas comment se passe cette réaction: $$\ce {HCl + KMnO4 -> KCl + MnCl2 + Cl2 + H2O}$$ Ce que je sais: 1) $$\ce {HCl}  se dissocie en$$\ce {H +} $et$$\ce {Cl -}$. KMnO4 is a strong oxidising agent which oxidises (increases the oxidation state of the element or removes electrons in isolated or combined state with other element), KMnO4 is added to a round bottom flask and then HCL is added via an addition funnel at a pretty slow rate. O Both HC1 and KMnO4 acts as oxidising agents. * 2 KMnO4 + 3 H2SO4====> K2SO4+ 2MnSO4 + 3 H2O + 5(O) 1. The reaction mixture was stirred at 85 C for 6 h.

HCL being a strong electrolyte dissociates in water to give H+ and Cl- ions. (0.05, 2, 25) PP → polypropylene film oxidized in KMnO 4 /HCl 0.05/0.10 mol L −1 solution for 2 h at 25 °C. Examples: Notes: Note that in example 2 the extra carbons are cleaved to give the same product as in example 1. This is why you have 16H+(aq) and only 10 Cl-(aq) in the NET equation, which might confuse you because everyone knows that HCl has one atom of each. PartIn acidic medium ie., acidified KMnO4 oxidises FeSO4 to Fe2(SO4)3 and it itself gets reduced to MnSO4. This equation is a bit tricky because some of the Cl- ions do take part in the reaction and some do not. This is a redox reaction KMnO4 + NaI + NaCl → Drop the spectator ions, establish the products. 1 Answer The filtrate was concentrated to half its volume, then acidified with 1.5N HCl (500 mL) to pH ~2 Sushi F. asked • 04/27/14 potassium permanganate reacts with hydrochloric acid forms potassium chloride, manganese chloride, chlorine and wate Standardization of Potassium Permanganate (KMnO4) solution with standard Sodium Oxalate solution.doc Each polymer was submitted to eight distinct oxidation conditions and named accordingly, e.g. Step 7. first u need to define which atoms got oxidation # changed.
