Why hcl should not be used for potassium permanganate titrations

hello student question is why permanganate titration in the presence of hydrochloric acid are unsatisfactory write ok as we know that when we use hydrochloric acid in the permanganate titration so the results are not that accurate OK Here The hydrochloric acid in this titrations when we use hydrochloric acid in the permanganate titration the results are unsatisfactory right so the reason behind this as we know that the h + ions right here acid is needed to provide the X + ions so that the reaction occurs ok here we see acid right acid which is needed which is needed to provide the h + ions right which is needed to provide the h + Ion so that here so that a particular reaction occurs right so that particular reaction occurs ok so hair if we use HCL OK Here were used instead of ok instead of H2 S o4 acid H2 S o4 acid then what happen then the permanganate Ion right for magnet science would oxidize the chloride ions and to form the cl2 gas right here then when we use their HCL then what happened then the form manganate permanganate ion what they do they David oxidizer oxidize from the chlorine gas at chlorine gas and hair it would be not available to react with the oxalic acid right here so it would not would not be available to react with oxalic acid know that HCL right HCL which is a stronger Acid which is a stronger acid than the oxalic acid right then the oxalic acid ok so here when HCL it is much stronger than the auxiliary acid than what it do then it will react with th...

Table of Contents • • • • • • • • • • • Why is HCl not used in redox titration? Hydrochloric acid (HCl) is usually not used in the process of titration because it reacts with the indicator potassium permanganate (KMnO4) that is used in the process. It reacts with KMnO4 solution and gets oxidized which further results in the liberation of chlorine gas. Why HCl and HNO3 is not used in titration? HCl and HNO3 are not used in the titration of Mohr’s salt in place of sulfuric acid because: HCl is a mild reducing agent and it reacts with some of the indicator that is KMnO4 solution so the final value of the indicator used come to be more than the actual value disturbing the experiment. Why we are using sulfuric acid instead of hydrochloric acid in the redox titration? Sulfuric acid is used because it is stable towards oxidation; whereas, for example, hydrochloric acid would be oxidized to chlorine by permanganate. What happens when nitric acid reacts with hydrochloric acid? Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO3 + 3 HCl → NOCl + Cl2 + 2 H2O. Why is HCl not used? HNO3 . Hint : $ HCl $ is not used in the titration with $ KMn$ oxidizes the HCl into chlorine gas. Why can’t we use hydrochloric acid or nitric acid for manganate(VII) redox titration? Permanganate titration. Qn: Why can’t we use hydrochloric acid or nitric acid for manga...

Why is HCl not used to make the medium acidic in oxidation reactions of $KMn$ acts as a reducing agent in the presence of HCl Hint: Chlorine gas acts as an oxidizing agent and gets reduced. This is due to the fact that it has the ability to gain electrons. Potassium permanganate $KMn$ and provides a perfect acidic medium. This is practically applied in doing the titrations.

Hydrochloric acid (HCl) is usually not used in the process of titration because it reacts with the indicator potassium permanganate (KMnO4) that is used in the process. It reacts with KMnO4 solution and gets oxidized which further results in the liberation of chlorine gas. What will happen if HCl is used in titration? As it is added, the HCl is slowly reacted away. The point at which exactly enough titrant (NaOH) has been added to react with all of the analyte (HCl) is called the equivalence point. Up to the equivalence point, the solution will be acidic because excess HCl remains in the flask. Can HCl or HNO3 be used in titration? HCl and HNO3 are not used in the titration of Mohr’s salt in place of sulfuric acid because: As dilute sulfuric acid is ideal for redox titration because it is neither an oxidizing agent and nor a reducing agent. Can we add HCl and HNO3 for acidification in titration of oxalic acid solution with potassium permanganate solution? KMnO4 is a dark colour solution so always use upper meniscus reading. Use sulphuric acid for acidifying the potassium permanganate. Don’t use HCl or nitric acid. Maintain the temperature of oxalic acid solution at 50-60’C. Why HCl Cannot be used to acidify KMnO4? KMnO4 is a very strong oxidizing agent and it can oxidize HCl to liberate chlorine gas, therefore HCl cannot be used to acidify potassium permanganate solution in volumetric analys...

Table of Contents • • • • • • • • Why acidified KMnO4 Cannot be acidified from HCl or hno3? KMnO4 is a very strong oxidizing agent and it can oxidize HCl to liberate chlorine gas, therefore HCl cannot be used to acidify potassium permanganate solution in volumetric analysis. Why HCl and hno3 are not used with KMnO4? The acid used in this titration is dilute sulphuric acid. Nitric acid is not used as it is itself an oxidising agent and hydrochloric acid is usually avoided because it reacts with KMnO4 according to the equation given below to produce chlorine and chlorine which is also an oxidising agent in the aqueous solution. Why can’t KMnO4 be acidified using HCl? KMnO4 is strong oxidizing agent and it oxidize HCl. Permanganate will react with hydrochloric acid to liberate chlorine. Hence HCl is not used to acidify a permanganate solution in volumetrically. Can we add HNO3 or HCl for acidification in titration of oxalic acid with potassium permanganate solution? KMnO4 is a dark colour solution so always use upper meniscus reading. Use sulphuric acid for acidifying the potassium permanganate. Don’t use HCl or nitric acid. Maintain the temperature of oxalic acid solution at 50-60’C. Why HCl and HNO3 is not used in electrolysis of water? This is because nitric acid is a strong oxidising agent, and oxidises hydrogen gas to convert it into the water. Why is HCl not used to prepare HNO3? HCl is not used as a reactant in the laboratory preparation of nitric acid. HCl is a volati...
