We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.

What is the effect of discolored agno3 in the titration with kscn?

Discolored AgNO3 in the titration with KSCN may indicate the presence of impurities or decomposition of the solution. This can lead to inaccurate results in the titration as the discolored solution may not react as expected with KSCN. It is important to use a fresh and clear AgNO3 solution for accurate titration results.


What is the pH of KSCN?

The pH of a solution of potassium thiocyanate (KSCN) will depend on the concentration of the solution but will likely be close to neutral (around 7) since KSCN is a salt and will dissociate into its ions in water.


What results when you have fecl3 and kscn and agno3?

When you mix FeCl3 and KSCN, a blood red color forms due to the formation of Fe(SCN)2 complex. When AgNO3 is added to this solution, a white precipitate of AgSCN is formed, indicating the presence of thiocyanate ions in the solution.


How do you prepare0.1N KSCN soln?

To prepare a 0.1N potassium thiocyanate (KSCN) solution, dissolve 2.01 grams of KSCN in distilled water and dilute to 1 liter. Be sure to use a volumetric flask for accuracy and precision in preparing the solution.


What colour is obtained on adding KSCN reagent to ferric ion solution?

A blood-red color is obtained when potassium thiocyanate (KSCN) reagent is added to a ferric ion solution. This color change is due to the formation of a ferric thiocyanate complex.


Will KSCN react with water?

It will not react with, but it will dissolve IN water, giving free K+ and SCN- ions.


Why is KSCN used in iodometry of copper?

On addition of the KI to your copper (II) solution, you formed Copper (I) iodine solid and produced the tri-iodide ion. It is the tri-iodide ion that you are titrating with the sodium thiosulfate. The tri-iodine ion is what itercalates into the starch molecules to form the dark blue color you are using as an end point in the titration. Some the the tri-iodide ion formed will adsorb to the surface of the solid copper (I) iodine formed. This must be desorbed for a complete titration. The addition of the potassium thiocyanate, displaces the adsorbed tri-iodine ion, and liberates it for titration.
