Flashcards in Identifying Ions Deck (10)
Add HCl and pass the released gas through limewater to form a cloudy white precipitate
If you add silver nitrate solution, forms white precipitate
If you add nitric acid, forms insoluble precipitate but then after adding NH4OH, the precipitate dissolves
This ion turns red litmus paper blue
Forms a white precipitate with BaCl2 and this precipitate is insoluble in HCl
Add HCl and test the gas released with lead acetate paper. The rotten-egg-smelling gas turns the paper brown-black.
After adding strong base and gently heating, smells like ammonia.
Ferrous or Iron (II)
If you add potassium ferrocyanide (K3Fe(CN)6), a dark blue (Turnball's blue) precipitate forms
Ferric (Iron (III))
Forms a Prussian blue (dark blue) precipitate with potassium ferrocyanide
Turns blue litmus paper red
