What was the purpose of the Iron titration?
The purpose of this experiment was to determine the percentage purity of the iron (II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent, with unknown sample dissolved in deionized water.
Which is the correct formula for iron ( II ) salt?
MnO4- + 4H+ +3e- MnO2 + 2H2O Fe2+ → Fe3+ + e− The Permanganate was reduced to form MnO2 indicated by a change from purple colour, while the Iron was oxidized to form an iron (III) ion. In the 2nd part: The percentage purity of iron (II) Salt , an unknown sample of Impure Iron (II) salt was weighed to 1.322g.
How is potassium permanganate used in the analysis of iron?
We will use potassium permanganate, KMnO4, as the titrant in the analysis of an unknown sample containing iron to determine the percent iron by mass in the sample. In acidic solution, potassium permanganate rapidly and quantitively oxidizes iron(II) to iron (III), while itself being reduced to manganese(II).
How is the concentration of iron determined by colorimetry?
Fe3+ (aq) + SCN− (aq) → [FeSCN]2+ (aq) By comparing the intensity of the colour of this solution with the colours of a series of standard solutions, with known Fe3+concentrations, the concentration of iron in the tablet or food sample may be determined. This technique is called colorimetry.
