Why we ad sulpheric acid with oxalic acid?
we add sulpheric acid with oxalic acid to stable the ions when titrated against KMNO4
Can someone help with this chemical equation K4FeC6N6 plus KMnO4 plus H2SO4 KHSO4 plus Fe2S3?
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
Why is brown turbidity found in titrating KMnO4 solution with oxalic acid?
Brown turbidity in a titration of KMnO4 with oxalic acid typically arises from the formation of manganese(II) ions during the reaction. When KMnO4, which is purple, is reduced by oxalic acid, it produces manganese(II) ions, which can form a brown precipitate of manganese(IV) oxide (MnO2) in certain conditions. This turbidity indicates the presence of manganese species that are not fully soluble, often due to incomplete reduction or changes in pH during the titration.

Is potassium sulfate possible as a byproduct of manganese heptoxide synthesis?
Yes; the chemical reaction is:2 KMnO4 + 2 H2SO4 → Mn2O7 + H2O + 2 KHSO4
What is the oxidising agent in kmno4 h2c2o4 h2so4?
In this reaction, potassium permanganate (KMnO4) acts as the oxidizing agent. It oxidizes oxalic acid (H2C2O4) to carbon dioxide and sulfuric acid (H2SO4) helps to provide the acidic conditions needed for the reaction to occur.
Balanced equation for oxalic acid and potassium permanganate?
The balanced equation for the reaction between oxalic acid (H2C2O4) and potassium permanganate (KMnO4) in acidic solution is: 5 H2C2O4 + 2 KMnO4 + 3 H2SO4 → 10 CO2 + 2 MnSO4 + 8 H2O + K2SO4
Why you add h2so4 to the kmno4 titration?
consider the balance chemical equation, suppose the reaction with oxalic acid 2MnO4- + 16H+ + 5C2O4 --> 2Mn+2 + 8H2O + 10CO2 Above reaction shows that the reaction requires a number of protons to occur, H2SO4 is the source of these protons.
Why use h2so4 instead of hcl in titration of kmno4?
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.

Can someone help with this chemical equation K4FeC6N6 plus KMnO4 plus H2SO4 KHSO4 plus Fe2S3?
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.
Why H2So4 is used in acidification of KMno4 solution not HCl or HNo3?
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.
Why is brown turbidity found in titrating KMnO4 solution with oxalic acid?
Brown turbidity in a titration of KMnO4 with oxalic acid typically arises from the formation of manganese(II) ions during the reaction. When KMnO4, which is purple, is reduced by oxalic acid, it produces manganese(II) ions, which can form a brown precipitate of manganese(IV) oxide (MnO2) in certain conditions. This turbidity indicates the presence of manganese species that are not fully soluble, often due to incomplete reduction or changes in pH during the titration.
Why is dilute h2so4 most suitable as compared to hcl and hno3 in kmno4 titrarion?
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.
Why is Brown turbidity sometimes seen while titrating KMnO4 solution with oxalic acid?
Brown turbidity may be observed when titrating KMnO4 with oxalic acid due to the formation of manganese dioxide (MnO2) as a byproduct. This occurs when excess oxalic acid reduces MnO4- to Mn2+ ions, which then react with oxygen in the air to form manganese dioxide. The brown color of MnO2 leads to turbidity in the solution.
What is formed in the titration of FeCl2 with KMnO4 with H2SO4 present?
In the titration of FeCl2 with KMnO4 in the presence of H2SO4, iron(II) ions (from FeCl2) are oxidized to iron(III) ions by the permanganate ions from KMnO4. The balanced chemical equation is: 5Fe^2+ + MnO4^- + 8H^+ ---> 5Fe^3+ + Mn^2+ + 4H2O
Why brown turbidity found in titrating KMno4 with oxalic acid?
Brown turbidity in the titration of KMnO4 with oxalic acid may be due to the formation of manganese dioxide (MnO2). This reaction occurs in acidic conditions and indicates that the end point of the titration has been reached. MnO2 is insoluble and can appear as a brown precipitate, causing turbidity in the solution.
