Final answer:
To determine the copper(II) sulfate concentrations in the two unknown samples, use the calibration plot to compare the measurement signal of the unknown samples to the corresponding concentration on the plot.
Step-by-step explanation:
To determine the copper(II) sulfate concentrations in the two unknown samples, you will need to use the calibration plot. The calibration plot is a graph that shows the relationship between the concentration of a substance and the measurement signal, such as absorbance or fluorescence intensity. In this case, you can use the calibration plot to determine the copper(II) sulfate concentrations by comparing the measurement signal of the unknown samples to the corresponding concentration on the plot.
Start by plotting a calibration curve using known concentrations of copper(II) sulfate and their corresponding measurement signals. Then, measure the measurement signal of the unknown samples, and determine their corresponding concentrations by finding the corresponding point on the calibration curve.
