Answer :
In this section, you will be working with different red food coloring solutions with known concentrations (2.00 ppm, 4.00 ppm, 6.00 ppm, 8.00 ppm, and 10.00 ppm).
Your task is to click on each picture representing these solutions and record the "Absorbance at max" value exactly as given in the picture. Additionally, you need to do the same for an unknown solution.
To begin, locate the red food coloring solutions with known concentrations (2.00 ppm, 4.00 ppm, 6.00 ppm, 8.00 ppm, and 10.00 ppm). Click on each picture and note down the "Absorbance at max" value provided in the picture. The "Absorbance at max" is a measure of how much light is absorbed by the solution at its maximum absorption wavelength.
Repeat the same process for the unknown solution. Click on the picture representing the unknown solution and record its "Absorbance at max" value. This value will help determine the concentration of the unknown solution.
By comparing the absorbance values of the known solutions with their corresponding concentrations, you can create a calibration curve. This curve will allow you to determine the concentration of the unknown solution based on its absorbance value. The relationship between concentration and absorbance is typically linear, so you can use this calibration curve to find the concentration of the unknown solution.
Remember to record the "Absorbance at max" values accurately, as they will be crucial for determining the concentration of the unknown solution.
