When potassium permanganate (KMnO4) reacts with hydrochloric acid (HCl), the manganese in KMnO4 gets reduced from a +7 oxidation state to a +2 oxidation state, forming MnCl2, while the chlorine in HCl gets oxidized to form Cl2 gas. The overall balanced equation is 2KMnO4 + 16HCl -> 2KCl + 2MnCl2 + 5Cl2 + 8H2O.
The balanced equation for KMnO4 plus HCl is: 2KMnO4 + 16HCl -> 2KCl + 2MnCl2 + 8H2O + 5Cl2
H2SO4 is typically used instead of HCl in the titration of KMnO4 because HCl can react with KMnO4 and form chlorine gas, which can interfere with the titration results. Additionally, H2SO4 provides the required acidic medium for the reaction to occur between KMnO4 and the analyte.
HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
HCl is not used in redox titrations of ferrous ion with KMnO4 because it can react with KMnO4 and interfere with the titration process. HCl can reduce KMnO4, which would lead to inaccurate results by altering the equivalence point of the titration. Instead, a buffer solution is often used to maintain a constant pH during the titration.
Yes, potassium permanganate (KMnO4) can be acidified with both hydrochloric acid (HCl) and nitric acid (HNO3) to increase its reactivity. Acidification helps to enhance the oxidizing power of KMnO4 in redox reactions.

Yes, potassium permanganate (KMnO4) can be acidified with both hydrochloric acid (HCl) and nitric acid (HNO3) to increase its reactivity. Acidification helps to enhance the oxidizing power of KMnO4 in redox reactions.
H2SO4 is used in acidification of KMnO4 solution because it is a stronger acid compared to HCl or HNO3, which ensures complete dissociation of the acid and provides a higher concentration of H+ ions for the redox reaction to occur efficiently. Additionally, H2SO4 is not easily oxidized by KMnO4, unlike HCl or HNO3 which could interfere with the redox reaction.
KMnO4 is not prepared using HCl acid because the acidic conditions would reduce the permanganate ion to manganese dioxide. Instead, it is typically prepared using a basic solution like KOH to maintain the permanganate ion in its oxidized state.
The chemical equation for the reaction between hydrochloric acid (HCl) and lithium hydroxide (LiOH) is: HCl + LiOH -> LiCl + H2O This reaction produces lithium chloride (LiCl) as a salt and water (H2O) as a product.
Dilute H2SO4 is preferred over HCl and HNO3 in KMnO4 titrations because H2SO4 does not oxidize the Mn present in KMnO4, maintaining its stability. On the other hand, HCl and HNO3 can oxidize Mn in KMnO4, interfering with the titration results. Additionally, H2SO4 helps to acidify the solution and provide the necessary hydrogen ions for the reduction-oxidation reaction to proceed effectively.
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
When ethanol reacts with excess acidified KMnO4, it is oxidized to form ethanoic acid. The purple color of KMnO4 is decolorized to colorless Mn2+ ions during the reaction.
