Drop a solution of this in Sodium hydroxide solution, you will see a greenish precipitate instantly, this is the test for Iron(II) ions. Note that after sometime, the Greenish precipitate will turn to reddish.

--------------------------------------------------
1) Add a few drops of dilute sodium hydroxide to the solution that you want to test for iron ions
2) A precipitate will form
3) If the precipitate is green, this indicates the presence of Fe (iron) 2+ ions. If the precipitate is red-brown, this indicates the presence of Fe (iron) 3+ ions.

Why does copper solution stick to iron nails?
Iron is more reactive than copper, so the copper precipitates out of the solution by sticking to the iron. For example, if you have a test tube with a solution of copper (II) sulfate and put an iron nail into it, the iron will react with the solution to form iron (II) sulfate and the copper will come out of the solution and stick to the iron.
When iron II sulphate reacts with ammonia would it form iron hydroxide or ferrous ammonia sulphate or ammonia iron II sulphate?
ammonium iron (II) sulphate.
What is produced with iron and copper II chloride?
copper and iron (II) chloride
What is the formula for iron(II) sulfate?
The formula for Iron(II) sulfate is FeSO4.
What tablet is dropped into a test tube of urine to test glucose?
clinicik test
What is the result with iron II chloride in the test flame?
Iron has a yellow-gold color in the flame test.
Why does copper solution stick to iron nails?

What is the pH of iron ii sulfide?
Iron(II) sulfide is insoluble in water.
What is the formula for iron(II) sulfate?
The formula for Iron(II) sulfate is FeSO4.
What is the correct name for compound FeS?
iron sulphide, iron(II) sulphide or ferrous sulphide. Iron sulphide is ambiguous however and could refer to any one of a range of iron sulphur compounds,including Fe3S4 and Fe2S3
How will you synthesize Iron II bromide from Iron II carbonate?
Reacting Iron(II) carbonate with Hydrobromic acid produces Iron(II) Bromide, water and Carbon dioxide. FeCO3 + HBr ----> FeBr2 + H2O + CO2
What tablet is dropped into a test tube of urine to test glucose?
clinicik test
What is chemical name for FeSO4?
Iron (II) sulfate is the correct name for this compound. The Fe ion has a charge of 2 and so does the sulfate ion, so there is no subscript after them.
