- Redox titration analysis (Iron)
- Accurately weigh sample.
- Dissolve the sample into a known volume in a volumetric flask.
- Put manganate into burette.
- Pipette the sample into a conical flask.
- Add sulphuric acid to the manganate.
- Titrate until the first permanent colour change.
- Repeat until results are concordant.
- This is to prevent the original result from being anomalous and to remove and anomalies from the results.
- Concordant results are within 0.1cm of each other.
- This should be pale pink.
- Repeat until results are concordant.
- Titrate until the first permanent colour change.
- Add sulphuric acid to the manganate.
- Pipette the sample into a conical flask.
- This allows the calculation of the concentration of the metal, by working it out against the amount of sulphuric acid needed to neutralise it.
- Put manganate into burette.
- Dissolve the sample into a known volume in a volumetric flask.
