How do spectrophotometers work?
How do spectrophotometers work? The basic function of a spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it through a computer.

Why can iron form fe3+ and fe2+?
Why can iron form fe3+ and fe2+? It’s essentially about isolated atoms. Fe+2 and Fe+3 are ionization states of iron in molecules or solids. The ultimate reason why both kinds of ions are stable is that 3 electrons are weakly enough held to each Fe atom that they can be pulled away by strong electronegative […]
