Lab 9 Emission Analysis of Aqueous Solutions of Group IA and lIA Metal Salts Emion Analysis of Aqus Seltions of Gros A and BA Metal Salts 3. Identify the metal ions present in each of the following water sample emission spectra. Use the data in the Table in Question 2 to assist you in identifying the metal ions present in each spectrum Water Sample 1 75 nm and 771 m 672 nm 3900 603 nm 2900 554 pm 1900 900 -100 400 750 450 500 550 600 650 700 800 Wavelength, nm Identity of metal ions in unknown water sample 1. Water Sample 2 589 pm 2950 2450 606 nm 1950 672 n 1450- 950- 829 nm 740 m 450 - -50 200 300 400 500 600 700 800 900 Wavelength, nm Identity of metal ions in unknown water sample 2.

Answer 1

Generally to identity the metals we use plans tests d e eenknown Samples & by knowing the cold og particulat U of Or ermitted sample we cow the egg what region the that particule as colch absets by encregoing sectione transistions. & usually in the above question is identifying the know metals we need to compare this spection with the Eiginal Spectrum of me values of the alkat & allarsne retals By knowing ware lengths of observed spectrum we can assign The colors to which warteryth legion it belongs In water Sample - the wavelengthy are 554nm, 60300, 672 nm, 765002 771 nom & colds to je the particulel legions are homegleen, Red, violet
