Why are titrations using permanganate performed in acidic solutions?
Titrations using permanganate are performed in acidic solutions to prevent the premature reduction of permanganate ion to colorless manganous ion. The acidic conditions stabilize the permanganate ion and ensure a more accurate endpoint detection during the titration.
What is titration and what is the purposeof titration?
Titration is the process of determining the concentration of a substance of a given solution using a known reagent. So types of titrations are neutralization titrations, red-ox titrations, gravimetric titrations and colorimetric titrations. According to the reagents available, the best type of titration should be determined.
Why is water not used in the electrolysis of copper permanganate solution?
Water is not used in the electrolysis of copper permanganate solution because water will compete as an electrolyte and interfere with the desired redox reactions happening at the electrodes. Using water as an electrolyte would form other byproducts instead of the intended products of the copper permanganate electrolysis. This could lead to inefficient and unpredictable results in the process.
What is neutralization titrations?
Neutralization titrations are a type of volumetric analysis that involve determining the concentration of an unknown acid or base by reacting it with a standard solution of an acid or base of known concentration. The endpoint of a neutralization titration is typically marked by a color change using an indicator or by monitoring the pH of the solution. This method is commonly used to determine the amount of acid or base present in a solution.
How do you redox titration by Potassium Permanganate?
In a redox titration using potassium permanganate, the permanganate ion (MnO4-) acts as the oxidizing agent while the other substance being titrated acts as the reducing agent. The endpoint is reached when all the reducing agent has been consumed, leading to a color change from purple to colorless or light pink. The volume of potassium permanganate solution required to reach the endpoint is used to calculate the concentration of the reducing agent.

Conclusion for the determination of iron by permanganate?
The conclusion for the determination of iron by permanganate is that oxidation of iron is one of the most popular titrations. All permanganate titrations, when used as a titrant, should use different techniques to read volume of liquid in the burette.

Why is KMnO4 not prepared using Hcl acid?
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.
What is the difference between aqueous and non aqueous titration?
Aqueous titration involves using a water-based solvent for both the titrant and the analyte, while non-aqueous titration involves using a solvent other than water. Aqueous titrations are more common and are used for analyzing compounds that are soluble in water, while non-aqueous titrations are used when water may interfere with the reaction or when the compounds are not soluble in water.
How long does potassium permanganate take to dissolve in water?
Potassium permanganate typically dissolves in water within a few minutes, as it is a highly water-soluble compound. Agitating the solution or using warm water can help speed up the dissolution process.
What are complexometric titrations?
Complexometric titrations are a type of volumetric analysis where a complex-forming agent is used as the titrant to determine the concentration of a metal ion in a solution. This method is particularly useful for quantifying metal ions that form stable complex compounds. The endpoint of the titration is usually detected using a color change indicator or by monitoring a change in pH.
What is different to a titration done in school to one done in industry?
In industry, titrations are often automated using advanced equipment to ensure accuracy and efficiency. Industry titrations may involve larger sample sizes, more sophisticated analytical techniques, and stricter quality control measures compared to those conducted in school laboratories. Additionally, the scale and impact of the results obtained from industrial titrations are usually much greater than those performed in educational settings.
Ferrous oxalate reaction with potassium permanganate?
Potassium permangante, being a very strong oxidizing agent, oxidizes both the Fe2+ ion and the oxalate ion. Redox reactions are shown below: Oxalate oxidation: 2MnO4- + 16H+ + 5C2O42- ---> 2Mn2+ + 8H2O + 10CO2 Iron(II) oxidation: MnO4- + 8H+ + 5Fe2+ ---> Mn2+ + 4H2O + 5Fe3+ Moreover, if one needs to determine the exact percentage of oxalate and ferrous ions in solution, a titration is carried out using the permanganate, which will react with both the oxalate and ferrous ions. But, the carbon dioxide is liberated from the soution now, and zinc is added whch reduces the Iron(III) back to Iron(II). Another titration is then carried out using the permanganate, which gives a reading for the Iron(II) in solution only.
