KMnO4 depends on the reaction conditions. In our reaction, the product formed from Fe2+(aq) is Fe3+(aq) and possible products from the MnO 4 – ion are Mn2+(aq), Mn3+(aq), MnO2(s), or MnO 4 2–. The reaction product and the number of electrons gained by KMnO4 must be known before using the reagent in analytical determinations. Thus, you will use

I don't get how does this reaction of hydrochloric acid and potassium permanganate proceeds: $$\ce{HCl + KMnO4 -> KCl + MnCl2 + Cl2 + H2O}$$ What I know: $\ce{HCl}$ dissociates into $\ce{H+}$ Reaction depends on acidic medium & basic medium. KMno4 is a strong oxidizing agent. But stable oxidation no of mn in basic medium is +4 & +2 in acidic medium.so, in basic nedium mn is reduced to +4 oxidation state but in acidic medium it is reduc What is the reaction between KMnO4 and H2C2O4? Basically, we did a titration today which involved oxalic acid (H2C2O4) as the primary standard and used this to standardize a solution of KMnO4. We added to H2SO4 to the oxalic acid to introduce acid conditions, and we're currently doing redox. I have to work out the concentration of the Overall reaction:- 2KMnO 4 + 3H 2 SO 4 + 5(COOH) 2 → K 2 SO 4 + 2MnSO 4 + 8H 2 O + 10CO 2 Test Your Knowledge On Titration Of Oxalic Acid With Kmno4! Q 5.

Q 5. 2008-04-17 · Though it seems it may be a possible reaction between potassium permanganate and sodium hydroxide,but actually no reaction occurs, coz the product formed are KOH and NaMnO4 which are water soluble.so,it better to memorize that there is no reaction occurs between KMnO4 and NaOH. 1. KMnO4, NaOH 2.

Permanganate ion should be reduced to Mn^(2+). "Reduction half equation: "Mn(VII+) rarr Mn(II+) MnO_4^(-) +8H^(+) + 5e^(-) rarr Mn^(2+) + 4H_2O (i) "Oxidation half equation: "S(IV+) rarr S(VI+) SO_3^(2-) +H_2O rarr SO_4^(2-) + 2H^(+) + 2e^(-) (ii) Both equations are (I think) balanced with respect to mass and charge, as they must This is a redox reaction involving HCl and KMnO4. According to stoichiometry of the reaction 2 moles of KMnO4 will produce 8 moles of H2O .

If larger crystals of potassium permanganate are used the reaction is much slower. (For this reason you can use this demonstration while teaching kinetics.) Hint: This reaction can be delayed if the crystal size of the potassium permanganate is large. Discussion. The Error: equation KMnO4+ZnCl2=KMnCl4+ZnO is an impossible reaction Please correct your reaction or click on one of the suggestions below: KMnO4 + ZnCl2 = KCl + Zn(MnO4)2 KMnO4 + ZnCl2 = KMnCl2 + ZnO4 Instructions and examples below may help to solve this problem You can always ask for help in the forum Similar reaction takes place with KBr.
