Determining the Concentration of a Solution: Beer's Law

The primary objective of this experiment is to determine the concentration of an unknown nickel (II) Sulfate solutions that we made combining different amounts of the Nickel (II) Sulfate and water to determine how much light the solution absorbed. The machine, colorimeter will measures how much light passes through a liquid or how much light that liquid absorbs,  by taking different amounts of distilled water and Nickel (II) Sulfate solutions.
