WebApr 14, 2024 · Among them, Z13 has a smaller absorption peak area than Z0 and Z20, and the absorption peak wave number band is shifted to a lower wave number range. This indicates that the polymerization reaction occurred under optimal zeolite powder dosage, which consumed large amounts of calcium hydroxide and crystalline water. WebThe absorption is highest at around 510 nm (the wavelength at which absorption reaches its peak is called absorption maximum wavelength). This tells us that the iron solution should be measured at around 510 nm. … Thus, the properties of a substance can be investigated by measuring the spectrum. What is the significance of maximum absorption?

WebExpert Answer. 6. (10 points) An absorption spectrum shows those wavelengths of light which are absorbed by a substance. A peak in an absorption spectrum means that the wavelength at that peak is heavily absorbed by the substance. An absorption spectrum is measured by taking a gas or thin-film of the substance, directing light of various ... WebJan 23, 2024 · Absorption occurs when an electron in a chemical absorbs energy from the light, temporarily promoting the electron to a higher energy orbital. ...
