At a particular wavelength and with aid of the intensity of light emitted by a flame, plasma or spark, the atomic emission spectroscopy (AES) is used to determine the quantity of an element in a sample. (i). State a purpose of an internal standard in flame emission spectroscopy. (ii). Different metal-containing samples are brought into the flame to emit light based on each element's characteristic emission spectrum. Give the color of a flame and expected wavelenghts of sodium atomic ion (Na') and copper atomic ion (Cu2").
