Hi, how would I go about writing a balanced a ionic equation for Iron (II) with Sodium Hydroxide Soluation. What does it form. Iron Oxided and somthing else?

Fe²⁺ NaOH -> Fe²⁺O^2- +

is that write?

[Borek]

What is iron (II) hydroxide solubility?

What form does NaOH take in solution?

[thomas49th]

How do I find out?

[DevaDevil]

THAT my friend is basic knowledge - you just have to learn it. I am sure it is in your books.

[thomas49th]

hydrogen gas? what about sodium...ive nerver heard of NaH

[DevaDevil]

ok; as a follow up on boreks remark:

what is the solubility of sodium salts...
so what form does sodium hydroxide have in solution?

then will the sodium hydroxide solution form a precipitation with iron(II)? In other words: is the iron salt that will form soluble (no precipitation) or not.

[thomas49th]

It's the H+ ions that make an acid an acid, but sodium hydroxide is an alkali due to the OH- ions.
Acid + Metal = Salt +water

what's it for alkali + metal?

What is iron (II) hydroxide solubility?

So it makes FeOH + Sodium.... that seems unlikely. Am I misinterperting it?

I was wondering will it produce

NaFe + H₂0 but NaFe doesn't seem plausible...

[DevaDevil]

NaOH has like every sodium salt a high solubility so will fully dissolve into Na⁺ and OH^-

iron hydroxides have terrible solubilities so will precipitate.
you said in your question Fe(II), not metallic iron.

In this case Fe²⁺ (aq) + 2 OH^-(aq) --> Fe(OH)₂ (s)
the sodium will not actually do anything (spectator species).

[thomas49th]

Why would Iron displace sodium? Iron is far less reacitve...

[Borek]

There is no redox reaction going on here, all ions remain intact. You start with Na⁺ and Fe²⁺ on teh reactnats side and you have them on the products side - just Fe²⁺ are in the form of precipitated hydroxide.
