Why you do not use H2SO4 in iodometric titration?
Using H2SO4 in iodometric titration can lead to the formation of H2O2, which interferes with the reaction. It can also oxidize iodide ions prematurely, affecting the accuracy of the titration. Therefore, a different acid like HCl is typically used in iodometric titration.
What is the difference between potentiometer titration and electrochemical titration?
Potentiometric titration involves measuring changes in electrode potential to determine the endpoint of a reaction, typically using a pH meter. Electrochemical titration, on the other hand, involves measuring the electrical current generated by the reaction at the endpoint using techniques like coulometry or voltammetry. Both methods rely on differences in electrical properties for endpoint detection but differ in the specific measurements used.
Why do you need freshly prepared starch solution for iodometric titration?
because,starch undergoes a photochemical reaction. So, with the passage of time it can under go to the photochemical reaction and starch wouldnot be starch but it might have changed in anyother product. so...we should use freshly prepared starch.
What color indicates that a titration using phenolphthalein has reached the end point?
The color pink indicates that a titration using phenolphthalein has reached the end point.
What methods can be used to find the equivalence point in a titration experiment?
In a titration experiment, the equivalence point can be found using methods such as using a pH meter to detect a sudden change in pH, using an indicator that changes color at the equivalence point, or using a titration curve to identify the point of neutralization.

Difference between iodometry and iodimetry?
When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".

IF air oxidation of acid-iodide solution occurs what wiil happen to the iodometric titration?
Long story short, iodine in the solution made earlier through a reducing agent is weakly soluble and prone to loss to the air. Therefore, let's say you are using the titration to determine concentration of the titrant, the concentration would be off from the "true" concentration because you've lost some reactants.
What is another term for potentiometer?
A potentiometer and a rheostat are two different applications for a variable resistor.A potentiometer is a variable resistor, connected (using its three terminals) as a variable potential divider.A rheostat is a variable resistor, connected (using two of its three terminals) to adjust current.

Can you have viva questions on titration?
Yes, it is possible to have viva questions on titration. Some potential questions could focus on the principles of titration, the choice of indicators, calculations involved in titration, different types of titrations, sources of errors in titration, and applications of titration in various industries.
What is linearisation of potentiometer?
Linearization of the potentiometer refers to the inclination of the three parts of a potentiometer. The parts includes a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
