Beer's Law Colorimetry of Copper(II) Solutions

Copper (II) nitrate appears blue to the eye. This is because red light is absorbed and blue light is transmitted (Table 1). The amount of red light absorbed is directly proportional to the concentration of the copper (II) ions in the solution as defined by Beer's Law. In this experiment we will measure the absorbance of several copper (II

5 Easy Ways to Calculate the Concentration of a Solution

Feb 14, 2010In chemistry, a solution is a homogeneous mixture of two things a solute and the solvent that it's dissolved in. Concentration is a measure of how much solute is dissolved within the solvent. There are many reasons for calculating the concentration of a solution, but the chemistry involved is similar whether you're testing the chlorine level in a hot tub or performing life saving analysis on
