Determination of the strength of ferrous ammonium sulphate solution
During the titration, what is the role of K₂Cr₂O₇?
What is the oxidation state of chromium in K₂Cr₂O₇ before the titration starts?
What is the purpose of adding potassium iodide (KI) in the titration of CuSO₄ with sodium thiosulfate?
Which product is formed from the reduction of K₂Cr₂O₇ during the titration?
The color of the solution changes to blue at the endpoint of the titration because:
The molarity of FAS solution can be calculated if the volume and molarity of K₂Cr₂O₇ solution are known. This involves using:
