What is the theory of the redox titration?

Redox Titration refers to some titration based on the redox reaction between the titrant and analyte.

Acid base titration involves neutralization reaction between an acid and a base. whereas redox titration involves redox reaction between an oxidizing agent and reducing agent.

types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration

This is far to be a rule for this titration.

Titration is to be done at elevated temperatures to prevent side reactions

There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.

It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)

Because the endpoints are easily observed.

Iam not dut why you not answer me

I also don't know

Sulphuric Acid (H2SO4) is used in the redox titration process because it provides the H(+) ions necessary for the reaction to occur more quickly whilst the sulphate(-) ions barely react during the reaction.

HNO3 is not used in redox titration because being a good oxidising ageant it oxidises the compound itself whereas HCL is a very volatile and it takes part in the reaction therefore H2SO4 is used in the reaction

Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.

Zn + KNO3 + HCl → ZnCl2 + KCl + NH4Cl + H2O

Types of titration: 1) Acid-Base Titrations 2) Redox titrations 3) Complexometric Titrations 4) Zeta- potential Tittrations

Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.

i think ...one donate the electrons and other accept the electrons i.e one oxidized and other reduced. Raman sir what ever the defination ap jo diye na ,vo mujae half answer jise dikra hy, what v have learnt abt redox titration is all abt oxidation and reduction. In simple words " the principle involved in redox titration is accepting the electrons or donating the electrons simultaneously donating hydrogens or accepting the hydrogens."

A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.

The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.

No, they are not the same, but 1 is part of 2. Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.

The former is a acid base neutralisation reaction whereas the latter is a redox reaction.

If you are looking at a iodide to iodine redox titration, the solution would turn yellow instead of blue/black. The blue/black color of the iodine-starch complex is very intense and so the end-point is sharper. Without the starch, the endpoint, when the first yellow from the formation of iodine I2, appears, is less sharp and is harder to see.

Adding heat to a reaction usually speeds up a reaction.

Because sulphuric acid is non volatile and its sulphate ion is not interfering during the titration process while HCl is a volatile substance and its chloride ion interfere in the reaction as a reducing agent.

for preparing 0.1 normal solution of potassium permanganate you have to disssolve 3.16 g potssium permangnate in 1L water bt in alkaline or neutral medium reactions of potassium permanganate is different and Mn gains 3 electrons in redox reaction,so far alkaline medium redox titration equivalent wt of KMnO4 will be 158\3=52.6.so far,0.1 N KMnO4 in alkaline medium redox titration dissolve 5.26 g in 1L sol.

gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration

(1) io3- + 5i- + 6h+ ® 3i2 + 3h2o (2) i2 + 2s2o32- ® 2i- + s4o62-

Iron tablets can be powdered and analyzed potentiometrycally using Metrohm titrators with simple redox titration. Metrohm has a application bulletin dedicated for iron analysis.

With an acid (commonly used: acetic) CO2 is formed so oxygen from air is excluded in the oxidimetric titration reaction. It otherwise might interfere with the titrant.

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

A titration is done to determine the concentration of an unknown solution. As an example, consider a concentration unknown acid solution. It can be reacted with a known alkali, and the concentration of the acid can be calculated using the theory of stoichiometry.

During redox titration oxalic acid is a covalent compound and can not accept oxygen easily from an oxidizing agent so heat is necessary to break down the covalent bonding.

This is totally depending to WHAT KIND of analysis you are referring to. They could be of equal or of totally different value for one or another compound. Potentiometry is based on acid/base reactions and pH change at equivalence point, while conductometry is based in change of the (conductivity) behaviour of ions, also applicable to redox, precipitometric (argentometric) AND acid/base reactions.

Direct titration, Indirect titration, back titration, replacement titration and so on

The Redox 'Battlefield' is the Redox reactions mediated by bacteria.

Titration is a method of chemical analysis; for example: - volumetry - potentiometric titration - amperometric titration - radiometric titration - Karl Fisher titration - spectrophotometric titaration - viscosimetric titration and other methods

over titration is when too much titrant is added to the analyte in a titration procedure.

redox reaction involves a redox process. i.e. reduction (gain of electrons) and oxidation (loss of electrons)

H2SO4 is a strong acid and will deliver H(+) which will help to proceed the reaction much faster. Thereby, the sulphate-ions barely react in a redoxreaction. If we would take HCl for example, the Cl(-) ions can easily take part in a redoxreaction as a reductor.

What? A single replacement rxn is always a redox rxn, but all redox rxns are not single replacement.

It depends on the titration.

Double titration is a process were the first titration is used to standardize a titrant and the second titration is used to find the molarity of the unknow solution.

A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery. It is attached to an electrode and assists in transferring electrons between the electrode and a redox enzyme.

during a titration when a titrant completely furnished the sample then this is the end point of titration.

Yes some redox reactions can be reversible. An example of a reversible redox reaction is changing orange to blue which can continue to happen.

Redox reactions are divided into two main types. (i) Inter molecular Redox: In such redox reactions, one molecule of reactant is oxidized whereas molecule of other reactant is reduced. (ii)Intra molecular Redox: One atom of a molecule is oxidized and other atom of same molecule is reduced then it is intramolecular redox reaction. e.g., 2Mn2O7 4MnO2 + 3O2.

oxidation reaction + reduction reaction = redox reaction!

A redox reaction involves the transfer of electrons.

Combination reactions can be redox reactions.
