Measuring the concentration of a chemical in a solution is a common and important experiment in many fields of chemistry scientists may need to find the concentration of a pollutant in a given. In physical and analytical chemistry, colorimetry or colourimetry is a technique used to determine the concentration of colored compounds in solution the color or wavelength of the filter chosen for the colorimeter is extremely important.
Calorimetry is the measurement of the quantity of heat exchanged for example, if the energy from an exothermic chemical reaction is absorbed in a container of water, the change in temperature of the water provides a measure of the amount of heat. Colorimeter description 0358bt figure 1 the colorimeter 2 introduction the colorimeter is designed to determine the concentration of a solution by analyzing its color intensity monochromatic light from a led light source it is important to position the cuvette correctly in the.
Colorimetry is used in chemistry and in other sorts of places such as in industries colour printing, textile manufacturing, paint manufacturing and in food industries (including the chocolate industry) colorimetry is also used in asprin colorimetery can detect the smallest colour difference that. Calorimetry belongs to the most important experimental techniques it is the only experimental method allowing for direct measurements of various physical and chemical processes and reactions.
