Hcl is not used to acidify kmno4 solution

Table of Contents • • • • • • • • • • • Why is HCl not used in KMnO4 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 H2SO4 is used in titration of KMnO4 not HCl? Sulfuric acid is used because it is stable towards oxidation; whereas, for example, hydrochloric acid would be oxidized to chlorine by permanganate. Why is HCl not used to make the medium acidic in? Since, the reaction shows the formation of chlorine gas, which is itself a good oxidizing agent, therefore hydrochloric acid is not able to provide the acidic medium as potassium permanganate $KMn$ oxidizes the HCl into chlorine gas. What is the reaction between HCl and KMnO4? KMnO4 + HCl → KCl + MnCl2 + Cl2 + H2O. Why HCl is used in titration? During the course of the titration, the titrant (NaOH) is added slowly to the unknown solution. 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. What will happen if HCl will be used instead of H2SO4 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 v...

\[\ce\], which itself acts as an oxidizing agent and partly oxidises the reducing agent.

Table of Contents • • • • • • • • • • • Why is HCl not used with KMnO4? 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. What happens when HCl is added to KMnO4? KMnO4 + HCl | Potassium Permanaganate and Hydrochloric Acid Reaction. Aqueous hydrochloric acid (HCl) reacts with potassium permanganate (KMnO4) to produce potassium chloride (KCl), Manganese chloride (MnCl2), water (H2O) and chlorine gas (Cl2). Why is HCl or HNO3 not used to acidify 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 is KMnO4 solution not acidified with HCl But with H2SO4? For acidification of KMnO4 solution, only H2SO4 is suitable whereas the other mineral acids like HCl and HNO3 are not. HCl is not used because some of the KMnO4 will oxidize chloride ions to chlorine gas. Why hydrochloric acid should not be used for acidification? Because HCl is a concentrated acid and if we try to use it for acidifying water and put some of it in water, then it will burn us as steams will be released suddenly which will not give us a chance for escaping them. Thus, it is advised not to use Hcl f...
