Solute Concentration and Color Intensity

Try this

Using the Color Detector tool, measure the HEX values of various known concentrations of copper sulfate in an aqueous solution. Convert the HEX values to HSV (Hue, Saturation, Value) using an online converter. Plot mass of dissolved copper sulfate versus hue, and develop a mathematical model to describe the relationship.

Challenge yourself

• Determine the concentration of an unknown amount of copper sulfate based upon its hue value.
• Determine what will happen to the relationship after the saturation point has been reached.
