The reduction half reaction is the easiest: 5 e- + 8 H+ + KMnO4 →K+ + 4H2O + Mn2+ The oxidation side is a bit trickier because there are several possible products; Cl2, HClO, HClO2, ClO3-, and ClO4–. Use the upper one to read the volumes. 4. and requires that concentrated hydrochloric acid is employed. Answer to: Write the balanced equation for the reaction of potassium carbonate and hydrochloric acid. The strength of the solution should be taken till three decimals. Reaction of sodium bromide, potassium permanganate and hydrochloric acid. The pinkish color produced by the first drop of excess KMnO 4 signals the end point for the titration. This equation is a bit tricky because some of the Cl- ions do take part in the reaction and some do not. Potassium permanganate (KMnO4) reacts with hydrochloric acid (HCl) to form potassium chloride (KCl), manganese chloride (MnCl2), water (H2O), and chlorine gas (Cl2). Report 1 Expert Answer Best Newest Oldest. Theory: Potassium permanganate is a strong oxidising agent and in the presence of sulfuric acid it acts as a powerful oxidising agent. 1.
