The test tube was labeled with a tape‚ to signify 25 mL and the spectrophotometer was used to record the U-V visible ABS (absorbance spectrum) with the wavelength of 515. ● The 75 mL remaining solution was diluted with water‚ filling it to a 100 mL. Also‚ with a graduated cylinder 20 mL of these solution was measured and

experiment for the Spectrophotometric Determination of Equilibrium had the main objectives of determining the position of equilibrium and the formation of the equilibrium constant of the iron thiocyanate complex. In order to do so‚ the use of a spectrophotometer was incorporated into the experiment. In order to obtain an accurate end result‚ the absorbance of five various samples was used. In order to determine the formation equilibrium‚ the constant obtained from Beer’s Law was factored into the calculation

spectra produced when mater interacts with or emits electromagnetic radiation Meanwhile‚ spectrophotometry is the measurement of color in a solution by determining the amount of light absorbed in the ultraviolet‚ infrared‚ or visible spectrum. A spectrophotometer is an instrument often used to compare the intensity of light from a regulated or standard source with that of the intensity of wavelengths in a particular spectrum of light. The study of spectrophotometry is built on the belief that each chemical
