test for Copper(ll) ions?
when added to NaOH a Blue precipitate is formed
test for Iron(ll) ions?
when added to NaOH, a precipitate of (sludgy) green is formed
test for Iron(lll) ions?
when added to NaOH, a reddish brown precipitate is formed
test for ammonium compound?
Ammonium compound added to NaOH gives off ammonia gas
Test for carbonates
When HCl is added to a carbonates carbon dioxide gas is given off
Test for sulfate ions
a white precipitate of barium sulfate is produced when first HCl, followed by barium chloride is added to sulfate ions
Test for Chloride ions Cl-
when dilute nitric acid and silver nitrate are added to chloride ions, a white precipitate of silver chloride is fomed
Test for Bromide ions Br-
when dilute nitric acid and silver nitrate are added to bromide ions, a cream precipitate of silver bromide is fomed
Test for iodide ions I-
when dilute nitric acid and silver nitrate are added to iodide ions, a yellow precipitate of silver iodide is formed
Test for chlorine gas
bleaches damp litmus paper
Test for oxygen gas
oxygen relights a glowing splint
Test for carbon dioxide gas
carbon dioxide turns limewater cloudy when bubbled though
test for hydrogen gas
hydrogen makes a squeaky pop with a lit splint
test for ammonia gas
turns damp red litmus paper blue
test for water
water turns the white powder that is anhydrous copper(ll) sulfate into blue crystals (hydrated copper sulfate)
