Colorimeter (chemistry) A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths of light by a specific solution.
In this manner, what is a colorimeter and how does it work?
A colorimeter is an instrument which compares the amount of light getting through a solution with the amount which can get through a sample of pure solvent. A cloudy solution will simply scatter/block the passage of light (sometimes a colorimeter is used to monitor the growth of a bacterial or yeast culture).
What are the principles of a calorimeter?
A calorimeter is an instrument used in calorimetry for measuring the amount of heat released or absorbed in chemical or physical reactions. It can determine heat content, latent heat, specific heat, and other thermal properties of substances.
What is colorimetry and why do we use it?
In physical and analytical chemistry, colorimetry or colourimetry is a technique "used to determine the concentration of colored compounds in solution." The concentration of a sample can be calculated from the intensity of light before and after it passes through the sample by using the Beer–Lambert law.
