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