How do they use redox titration in real-world application?
Redox titration is commonly used in chemistry laboratories to determine the amount of a specific substance in a solution by measuring the amount of electrons transferred during the titration process. This method is used in various industries such as pharmaceuticals, environmental monitoring, and food and beverage production for quality control and analysis purposes.
Why is it necessary to acidify iron with h2so4 during redox titration?
Acidifying iron with H2SO4 during redox titration helps in preventing the hydrolysis of iron(III) ions, which can form insoluble hydroxides and interfere with the titration results. The acid medium also helps to ensure that the redox reaction between the iron and the titrant is carried out effectively and selectively.
Ten application of redox titration?
1-determination of ferrous [Fe+2] ion in a sample solution in(g\L).2-determination of (ferrous and ferric )in a mixture. 3-determination of purity of KClO3 sample. 4-determination of [fe+2] in unknown sample. 5-determination of total iron [Fe] in an iron ore. 6-determination of [Fe+3] in a sample. 7-determination of available chlorine in bleaching powder.
Why mohr's salt is used instead of ferrous sulphate in redox titration?
Mohr's salt (ammonium iron(II) sulfate hexahydrate) is used instead of ferrous sulfate in redox titrations because it is more stable and less prone to oxidation by air compared to ferrous sulfate. This helps in achieving more accurate and reliable results in redox titrations.
Is rust a redox reaction?
Yes, rusting is a redox reaction. It involves the transfer of electrons between iron and oxygen, resulting in the formation of iron oxide (rust).

Is a rusting car a redox reaction?
Yes, rusting in a car involves a redox reaction where iron in the metal reacts with oxygen in the air to form iron oxide (rust). In this reaction, iron is oxidized from its elemental state to iron oxide, while oxygen is reduced to form water.
Why ferroin indicator use?
Ferroin indicator is used primarily in titrations involving redox reactions, particularly for the determination of iron content in solutions. It changes color from blue to red upon reduction, allowing for easy visual detection of the endpoint in a titration. This property makes ferroin a valuable tool in analytical chemistry, providing a clear and straightforward method for monitoring changes in oxidation states during reactions. Its sensitivity and specificity for iron make it ideal for quantitative analysis in various applications.
How do you calculate redox number of batch for glass?
There are two redox , one is btach redox and another is glass redox . Glass redox is calculated as Redox =%FeO/total iron in glass as Fe2O3 This is very important factor in refining , color of glass . % FeO is calculated by IR transnmission and Total iron is determined by XRF or analytical method . Should you have question , contact us OGS Technology SMishra Shyambmishra@gmail.com
Why don't we use indicators in redox-titration?
Because the end point can easily be observed. Example: consider the titration between potassium manganate (IV) which is purple and ammonium iron (II) sulfate - colourless. At the end point the colourless standard solution will turn pale pink when the correct volume of deep purple titre is added. No indicator is required. Also this is not necessarily an acid base rxn
Why burning of fuel in oxygen and rusting of iron are considered as redox reaction?
There is a transfer of electrons during both reactions and that is what a redox reaction is.
Why nitric acid is used in volhard method?
Nitric acid is used in the Volhard method to oxidize Fe(II) to Fe(III) in order to prevent interference in the titration of chloride ions with silver nitrate. By converting Fe(II) to Fe(III), nitric acid ensures accurate and precise results in the determination of chloride content.
Determination of fe3 with EDTA by photometric titration?
Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
