Titrimetric redox determination of iron in an ore using dichromate a introduction many chemical compounds can be oxidized or reduced completely by reacting them with suitable reagents. Redox titration • redox titration is based on the redox reaction position of the end point properties of umass boston determine the end point • indicator electrode • redox indicators – the indicator has different color at reduction and oxidation • the end point determination – color change eg cu2+ + 2e → cu. Determination of iron ore by redox titration if the indicator reaction is reversible, the nernst equation applies e = e˚ + 005916 log {[inox]/[inred]} (4) the color change is observed when the titration mixture goes from one containing mostly. Permanganometric titration of iron (ii) - procedure and discussion general remarks oxidation of fe 2+ by permanganate is one of the most popular titrations however, while it looks very simple and straightforward, in fact to be accurate we have to take into account several factors.

  • Determination of iron by redox titration product with a simple but colorful titration a standard hcl solution will be provided to titrate all the ammonia contained in a sample of your copper(ii) compound since this is a strong acid-weak base titration, the equivalence point occurs at ph 7, and methyl orange is a good indicator to use.
