How To Make Beer's Law Plot In Excel

Jump to

    Creating a Beer's Law plot in Excel can be a straightforward process when you understand the steps involved. This guide provides a clear pathway to plotting absorbance versus concentration, helping you to visualize the relationship defined by Beer-Lambert Law.

    While Excel is a common tool for such scientific data analysis, our discussion will also cover how Sourcetable offers a more user-friendly alternative for constructing Beer's Law plots.

    Beer's Law Plot in Excel 2003

    Creating a Scatter Plot

    To graph the relationship between the concentration of a colored compound and light absorption, begin by opening Excel 2003. Insert your empirical data related to Beer's Law experiments into a worksheet. Select the data and use the 'Chart Wizard' to create a scatter plot. This plot will visually represent your data points.

    Scatter Plot for Titration Data

    For titration data, scatter plots can determine the equivalence point and construct pH titration curves. Input your titration data into Excel 2003. Use the 'Chart Wizard' to create a scatter plot. This will help in analyzing the titration process and finding critical points in your experiment.

    Adding Lines to Scatter Plots

    To add a smooth curve that connects data points in a scatter plot, use the 'Chart Options' within the 'Chart Wizard'. Select to add a trendline or smoothed line, which can aid in visualizing trends and patterns in your Beer's Law and titration data.

    Calculating Unknown Concentrations

    Once your scatter plot is created, you can use the trendline to calculate the concentration of unknown solutions. Analyze the plot to establish a correlation between known concentrations and absorption, which will then be applied to determine unknown concentrations.
