Answer to Question #207409 in Biology for Francesca

Question

The student is given sugar solutions with concentrations of 1%, 5%, 10% and 20%.

Explain how the student could use these solutions to estimate the concentration of sugar in the four fruit juices.

Please answer

Answer 1

The student can measure the absorbance of each of the given solutions by the spectrophotometer and build a calibration curve on this data. Subsequently, by measuring the absorbance of the four fruit juices and comparing the collected data with the calibration curve, it is possible to determine sugar concentration in them.
