What is the equation when a saliva is acidified with HCl and BACl. acidified with HNO3 and added with NH4MoO4. acidified with HCl and added with NH4C2O4?
saliva acidified with HCl and BaCl: Ba++ + SO42- ---> BaSO4 saliva acidified with HNO3 and added with NH4MoO4: H2PO4- + 12MoO42- +3NH4 +22 H3O+ ---> (NH4)3 + 12MoO3 + 34H2O saliva acidified with HCl and added with NH4C2O4: Ca++ + C2O4 ---> CaC2O4
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 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.
What is the product when ethanol react with excess acidified kmno4?
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.
What is the formula of acidified potassium permanganate?
There is not one formula for acidified potassium permanganate, it is a mixture, not a pure compound. Next to water it contains: H+ and K+ and MnO4- Warning: Do NOT use hydrochloric acid to acidify!

What happens when ethanol is oxidised with acidified kmno4 solution?
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.
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.
What is the balance equation for KMnO4 plus HCl?
2 KMnO4 + 16 HCl = 5 Cl2 + 8 H2O + 2 KCl + 2 MnCl2
What is the equation of the aldehyde plus acidified potassium permanganate?
The reaction between an aldehyde and acidified potassium permanganate (KMnO4) typically results in oxidation of the aldehyde to a carboxylic acid. The general equation for this reaction is RCHO + KMnO4 + H+ → RCOOH + MnO2 + K+.
Redox titrations of ferrous ion with KMnO4 why the HCl is not used in this reaction?
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.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
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.
What is the heat of neutralization between HCl and HNO3?
The heat of neutralization between HCl and HNO3 is approximately -57.3 kJ/mol. This value is the heat released when one mole of HCl reacts with one mole of HNO3 to form one mole of water and one mole of the salt nitric acid (HNO3).
