Explain why chlorine gas can be prepared by electrolyzing an aqueous solution of NaCl but fluorine gas cannot be prepared by electrolyzing an aqueous solution of NaF.
Note Set #11 – week 13 Analytical Chemistry ATOMIC SPECTROSCOPY Contains discrete transitions of rotational energy; one peak denotes one orbital transition −2 o E photon 2 where R = Rideberg Constant: 13.6 eV, z is charge, and n is principle quantum orbital # o 1240nm • eV / λ = eV; converting wavelength to eVolts o Calculating orbital transition energy 1 1 - ΔE = -R( 2− 2) = change in energy of e in units of eV - - nxis the orbital that an e is transitioning ty, n is the orbital e is transitioning from; after calculating ΔE, use guess and check to determine what the two principle orbitals are and compare against each other Atomization and Atomic Spectroscopy Types: samples are atomized in high heat conditions, then electron excitations are analyzed with different techniques o Atomic Emission Spec (AES): The heat source is used to both atomize samples, and also as the source of electron excitation. Electrons excited by the heat source emit radiation which is detected through a monochromator o Atomic Absorption Spec (AAS): sample is atomized by a heat source, then a hollow cathode lamp is used to shine light through the flame; the absorbance of light by the
