Question

what is the complete ionic equations of reactions of CsOH with FeCl2 ?

Answer 1

Answer:

Explanation:

Fe2+(aq)+2OH−(aq)→Fe(OH)2(s)⏐⏐↓

Explanation:

We first write down the balanced equation for this reaction:

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

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

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

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

+2Na+(aq)+2OH−(aq)→2Na+(aq)+2Cl−(aq)

+Fe(OH)2(s)⏐⏐↓

The final net ionic equation is now:

Fe2+(aq)+2OH−(aq)→Fe(OH)2(s)⏐⏐↓

The iron(II) hydroxide formed is easily oxidized when exposed to air and can easily become iron(III) hydroxide (Fe(OH)3).
