Question

What is the net ionic equation of the reaction of fecl2 with naoh?

Answer 1

Answer;

Fe2+(aq) + 2OH(aq) ----> Fe(OH)2(s)

Explanation;

We first write down the balanced equation for this reaction:

FeCl₂(aq) + 2NaOH(aq) → 2 NaCl(aq) + Fe(OH)₂(s)

This is a precipitation reaction, where two soluble salts are mixed together in solution forms to make a precipitate.

Then,we can now write the ionic equation for this reaction, that is:

Fe²⁺(aq) + 2Cl⁻(aq) + 2 Na⁺(aq) + 2OH⁻ (aq) → 2 Na⁺(aq) + 2Cl⁻(aq) + Fe(OH)₂(s)

Now, we need to cancel the spectator ions, which are ions that are present on both sides in the equation.

So, the equation becomes;

Fe2+(aq) + 2OH(aq) ----> Fe(OH)2(s)
