Answer #1

Experiment to determine Fe in apple/orange juice

Prepare standard solutions of Fe standard by mixing solutions of Fe3+ and NaSCN. The complex formed FeSCN2+ is analyzed specrophotometrically by observing the absorbance readings.

Plot a calibration curve. Find molar absorptivity of FeSCN2+.

Now take apple juiceorange juice and add known concentration f NaSCN to it. Complex formed is measured by absorbance readings.

Using, calibration curve, calculate the Fe concetration in the juice.

Determining vitamin c lab For two samples which were apple juice and lime juice. Did not extract because foods were liquids. Titrated with DCIP. Titration for apple juice was total amount of DCIP 10.33ml. How do I set up this problem to get vitamin c per ml solution??? Also standard titration of DCIP was 2.5 mg vitamin c / 13.38 ml DCIP= 0.187 mg vit c/ ml DCIP
