What is the function of NH4CNS in estimation of the amount of copper present in a supplied solution by iodometric method?
The end-point of the titration is more sharper if NH4CNS exist in the solution;
What is the function of phenolphthalein in titration?
to determine the end point of titration
What is the function of white tile in the acid-base titration experiment?
i case when the beaker get hot it does not affect the lab.
What is the function of an indicator in titration?
Change color

In a titration analysis what is the function of a meniscus finder?
It is helpfull for an accurate read-out of the volume scale.
What is a function of an indicator in a titration?
The function is to change color. This happens when all the H+ ( or H3O+) from the acid has been neutralized, an indicator in the sample will change
What are the type of conductometric titration?
types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration
What are complexometric titration method?
Direct titration, Indirect titration, back titration, replacement titration and so on
What is the function of starch solution in the redox 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-)
What is over-titration?
over titration is when too much titrant is added to the analyte in a titration procedure.
Which type of the analysis the titration is?
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
