Question

3. Identify the metal ions present in each of the following water sample emission spectra. Use the dat in the Table in Question 2 to assist you in identifying the metal ions present in each spectrum. Water Sample 1 672 nm 765 nm and 771 nm 39001 603 nm Intensity 1900 554 nm 900- -100- 400 450 500 700 750 800 550 600 650 Wavelength, nm Identity of metal ions in unknown water sample 1. Water Sample 2 589 nm 2950 1 2450 606 nm 672 mm Intensity 829 nm 1740 nm 950 200 300 400 700 800 900 500 600 Wavelength, nm Identity of metal ions in unknown water sample 2.

Answer 1

According to the given wavelength in the chart and compare them with the graphs ,it can be seen in water sample 1 metal ions present are Sr,K,Ca

And in water sample 2 metal ions present are Na,Sr,Ba( in a small amount)
