Question

Data Table 1. Anion Confirmation Tests.

Chemical	Anion	Addition of AgNO3	Addition of HCl
NaBr	Bromide	It became white and cloudy	Still was white and cloudy
Na2CO3	Carbonate	Clear inside white and cloudy around the outside	Still white and cloudy but bubbles start to form
NaCl	Chloride	Turn white cloudy on bottom clear on top	Still white cloudy on bottom clear on top
NaI	Iodide	In the middle very dark and cloudy fades out lighter white around the middle	Became a little separate
Na2SO4	Sulfate	Clear	Became white and cloudy
Na2S	Sulfide	Turn a brown color in the middle but separated from the clear	The brown becomes more separate from the clear
Unknown #103	CO3^2-	White and cloudy Small particles	Bubbles form white and cloudy
Unknown #104	S^2-	Turn brown color I the middle around clear	Some of the brown disappeared and become separate

Data Table 2. Cation Flame Tests.

Chemical	Cation	Flame Observations
KI	Potassium	LIGHT PINK
CaCl2	Calcium	RED
LiOH	Lithium	FUSHA PINK
NaCl	Sodium	ORANGE
Cu(NO3)2	Copper	TEAL
Unknown #105	Copper	TEAL
Unknown #106	Potassium	LIGHT PINK
Unknown #107	Calcium	RED

Data Table 3. Complete Chemical Identification.

Chemical	Cation	Anion Test Observations	Anion	Complete Chemical Name and Formula
Unknown #105	Copper	with AgNO3: No chane	No3^2-	Copper(II) nitrate, Cu(NO3)2
Unknown #106	Potassium	with AgNO3: In the middle very dark and cloudy fades out lighter white the middle	I-	Potassium iodide, KI
Unknown #107	Calcium	With AgNO3: Turn white cloudy on the bottom on top	Cl-	Calcium chloride, CaCl2

1. Use your results and observations in Data Tables 1, 2, and 3, to create a flow chart for the identification of an unknown (both an unknown anion and cation), using the AgNO₃ and HCl confirmation tests and the cation flame tests.
