I am trying to determine the net ionic equation for Fe(NO3) and K3 PO4, can you help, I'm having a difficult time?
Of course! I can help you determine the net ionic equation for the reaction between Fe(NO3)2 and K3PO4. To write the net ionic equation, we'll need to start by writing the balanced molecular equation and then proceed to write the ionic equation before ultimately converting it into the net ionic equation.
Step 1: Write the balanced molecular equation.
The reactants are Fe(NO3)2 (iron(II) nitrate) and K3PO4 (potassium phosphate). The molecular equation for their reaction can be written as follows:
Fe(NO3)2 + K3PO4 → FePO4 + 2KNO3
Step 2: Write the ionic equation.
Next, we need to write the ionic equation by dissociating all the compounds into their respective ions. The ionic forms of the above equation are:
Fe^2+ + 2NO3^- + 3K^+ + PO4^3- → FePO4 + 2K^+ + 2NO3^-
Step 3: Identify and eliminate the spectator ions.
In the ionic equation, we can see that the K^+ and NO3^- ions are present on both sides of the equation and do not participate in the net reaction. These are called spectator ions. So, we can eliminate them to write the net ionic equation.
Fe^2+ + PO4^3- → FePO4
Therefore, the net ionic equation for the reaction between Fe(NO3)2 and K3PO4 is Fe^2+ + PO4^3- → FePO4.
I hope this explanation helps!
Sure! I'd be happy to help you determine the net ionic equation for the reaction between Fe(NO3)2 and K3PO4.
To write the net ionic equation, we first need to determine the formulas for the products formed when these two compounds react.
The formula for Fe(NO3)2 is Fe2+ (aq) + 2NO3- (aq), and the formula for K3PO4 is 3K+ (aq) + PO4^3- (aq).
Now, let's see if any of the ions from the reactants combine to form insoluble compounds or precipitates.
According to solubility rules, most nitrate salts are soluble in water, so the Fe(NO3)2 will dissociate into Fe2+ and 2NO3- ions. Similarly, the K3PO4 will dissociate into 3K+ and PO4^3- ions.
The next step is to determine the complete ionic equation by swapping the ions that remain unchanged from the reactants to the products. So, we have:
Fe2+ (aq) + 2NO3- (aq) + 3K+ (aq) + PO4^3- (aq) → Fe2+ (aq) + 3K+ (aq) + 2NO3- (aq) + PO4^3- (aq)
Now, we can simplify the equation further by canceling out the spectator ions, which are the ions that do not participate in any actual chemical reaction. In this case, the spectator ions are the potassium ions (K+).
After canceling out the spectator ions, we have:
Fe2+ (aq) + 2NO3- (aq) + PO4^3- (aq) → Fe2+ (aq) + 2NO3- (aq) + PO4^3- (aq)
Finally, we can write the net ionic equation by removing the spectator ions that appear on both sides of the equation.
Net Ionic Equation:
Fe2+ (aq) → Fe2+ (aq)
So, the net ionic equation for the reaction between Fe(NO3)2 and K3PO4 is simply Fe2+ (aq) → Fe2+ (aq).
