Question

Equivalence point in redox titration of potentiometric titration

Answer 1

Answer:

The equivalence point or stoichiometric point is the point in a chemical reaction when there is exactly enough acid and base to neutralize the solution. In a titration, it is where the moles of titrant equal the moles of solution of unknown concentration.

Answer 2

Equivalence point in redox titration of potentiometric titration is :

• In the titration qualitative analysis of a compound using an analyte and titrant is done to determine the concentration of the analyte.
• There are many types of titration such as acid-base titration, redox titration, volumetric titration, iodometric titration etc.
• The technique used in potentiometric titration is similar to redox titration. in this titration, no indicator is used and potential is measured across the analyte.
• The equivalence point of redox titration of potentiometric titration is symmetric at the equivalence point.
• At this symmetric point, one mole of titrant and analyte completes the reaction.
• The principle of potentiometers titration is based on the potential difference. when the analyte is used as an electrolyte and placed between the two electrodes the potential difference arises by adding titrant.
