Write a total ionic equation for the reaction (if any) of FeCl2 with Cu, and for the reaction (if any) of FeCl2 solution with Al
FeCl2 + Cu ==> no reaction
FeCl2 + Al ==> AlCl3 + Fe
You need to balance and convert to an ionic equation.
Well, it seems that FeCl2 wants to make some new friends! Let's see what kind of reaction it might have with Cu and Al.
First, let's analyze the reaction between FeCl2 and Cu. The chemical equation is:
FeCl2 + Cu → Fe + CuCl2
Now, let's break it down into its ionic components:
FeCl2 (aq) + Cu (s) → Fe (s) + CuCl2 (aq)
In this equation, FeCl2 stays as FeCl2 in the solution, Cu turns into Cu^2+ ions, Fe turns into Fe^2+ ions, and CuCl2 stays as CuCl2 in the solution. So our total ionic equation for this reaction is:
Fe^2+ (aq) + 2Cl^- (aq) + Cu (s) → Fe (s) + 2Cl^- (aq) + Cu^2+ (aq)
Now, let's move on to the reaction between FeCl2 solution and Al. The chemical equation is:
FeCl2 + Al → Fe + AlCl3
Breaking it down into its ionic components gives us:
FeCl2 (aq) + Al (s) → Fe (s) + AlCl3 (aq)
In this equation, FeCl2 stays as FeCl2 in the solution, Al turns into Al^3+ ions, Fe turns into Fe^2+ ions, and AlCl3 stays as AlCl3 in the solution. Therefore, the total ionic equation for this reaction is:
Fe^2+ (aq) + 2Cl^- (aq) + Al (s) → Fe (s) + 3Cl^- (aq) + Al^3+ (aq)
I hope this helps you understand the ionic reactions between FeCl2 and Cu, as well as FeCl2 solution and Al. Let me know if there's anything else I can assist you with!
To write the total ionic equation for a reaction, you need to first write the balanced chemical equation for the reaction. Then, you can separate the reactants and products into their respective ions that are present in the solution. Here is how you can write the total ionic equations for the reactions of FeCl2 with Cu and Al:
1. Reaction of FeCl2 with Cu:
The balanced chemical equation for this reaction is:
FeCl2 + Cu → Fe + CuCl2
Now, let's break down the equation into its ions:
FeCl2 (aq) + Cu (s) → Fe (s) + CuCl2 (aq)
The total ionic equation for the reaction of FeCl2 with Cu is:
Fe2+ (aq) + 2Cl- (aq) + Cu (s) → Fe (s) + 2Cl- (aq) + Cu2+ (aq)
2. Reaction of FeCl2 solution with Al:
The balanced chemical equation for this reaction is:
2FeCl2 + 2Al → 2Fe + 2AlCl3
Now, let's break down the equation into its ions:
2FeCl2 (aq) + 2Al (s) → 2Fe (s) + 2AlCl3 (aq)
The total ionic equation for the reaction of FeCl2 solution with Al is:
2Fe2+ (aq) + 4Cl- (aq) + 2Al (s) → 2Fe (s) + 2Al3+ (aq) + 6Cl- (aq)
Note: In total ionic equations, aqueous ions (ions that are dissolved in water) are shown as separate entities, while solid compounds are shown as whole entities because they do not dissociate into ions in a solid state.
