Why you perform heating in redox titration?
Titration is to be done at elevated temperatures to prevent side reactions
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.
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."
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.
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.
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
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.
Is redox reaction always a single displacement reaction but a single-displacement reaction not always a redox reaction?
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.
