How can I get Fe+2 or Fe+3 ions in water? ?

Question

Are their colors different? Can they be precipitated?

Answer 1

When they react with NaOH,

Fe+2 is green colour.

Fe+3 is brown colour.

If you want to get Fe+2 or Fe+3 ions in water, you can try these ways.

If you want to get Fe+2 to Fe+3, just get some FeSO4 and drop it ito the water. Then, put a piece of Mg ribbon into the FeSO4.

If you want to get Fe+3 to Fe+2, just get some FeCl3 and drop it ito the water. Then, drop some chlorine water into the FeCl3.

Answer 2

an Fe^2+ solution is green and a Fe^3+ solution is red brown. they can precipitated by adding an aqueous solution of sodium hydroxide to these solutions. your first quesion has a simple answer,just dissolve a Fe^2+ or Fe^3+ salt in water
