What is photoelectric colorimetry?4 answersPhotoelectric colorimetry is a technique used to determine the concentration of a substance in a solution by analyzing the intensity of light transmitted through the solution. It involves passing a light beam of a specific wavelength through the solution, and measuring the amount of light absorbed by the solution. The absorption of light follows Beer-Lambert's law, which states that the amount of transmitted light decreases exponentially with an increase in the concentration of the absorbing medium. In photoelectric colorimetry, a colorimeter is used to detect the intensity of light transmitted through the solution. The light passes through the sample and is captured by a photodiode sensor, which converts the light into an output voltage. This voltage is then amplified and displayed on a device such as an Arduino with an LCD screen.
How can spectrophotometry be used to measure color?5 answersSpectrophotometry can be used to measure color by utilizing spectrometers and calibrated photographs. Portable spectrometers have made it simpler to measure color, but guidance on how to make these measurements has not kept pace.
