Write ionic equation for the following:
A. Na3PO4 + 3 AgNO3 --> 3 NaNO3 + Ag3PO4
B. (NH4)2SO4 + Ba(C2H3O2 + BaSO4
What's the problem with these? I assume they are in solution.
3Ag^+(aq) + PO4^3-(aq) ==> Ag3PO4(s)
A. The given chemical equation is:
Na3PO4 + 3 AgNO3 → 3 NaNO3 + Ag3PO4
To write the ionic equation, we need to separate all the soluble ionic compounds into their respective ions.
The soluble ionic compounds in this equation are:
- Na3PO4
- AgNO3
- NaNO3
Breaking these compounds into ions, we have:
- Na3PO4 → 3 Na+ + PO43-
- AgNO3 → Ag+ + NO3-
- NaNO3 → Na+ + NO3-
Now we can write the ionic equation using the ions:
3 Na+ + PO43- + 3 Ag+ + 3 NO3- → 3 Na+ + 3 NO3- + Ag3PO4
Simplifying the ionic equation:
PO43- + 3 Ag+ → Ag3PO4
Therefore, the ionic equation for the reaction Na3PO4 + 3 AgNO3 → 3 NaNO3 + Ag3PO4 is PO43- + 3 Ag+ → Ag3PO4.
B. The given chemical equation is:
(NH4)2SO4 + Ba(C2H3O2)2 → BaSO4 + 2 NH4C2H3O2
To write the ionic equation, we need to separate all the soluble ionic compounds into their respective ions.
The soluble ionic compounds in this equation are:
- (NH4)2SO4
- Ba(C2H3O2)2
- NH4C2H3O2
Breaking these compounds into ions, we have:
- (NH4)2SO4 → 2 NH4+ + SO42-
- Ba(C2H3O2)2 → Ba2+ + 2 C2H3O2-
- NH4C2H3O2 → NH4+ + C2H3O2-
Now we can write the ionic equation using the ions:
2 NH4+ + SO42- + Ba2+ + 2 C2H3O2- → BaSO4 + 2 NH4+ + 2 C2H3O2-
Simplifying the ionic equation:
SO42- + Ba2+ → BaSO4
Therefore, the ionic equation for the reaction (NH4)2SO4 + Ba(C2H3O2)2 → BaSO4 + 2 NH4C2H3O2 is SO42- + Ba2+ → BaSO4.
To write ionic equations, we need to first determine the dissociated ions of the reactants and products.
A. Na3PO4 + 3 AgNO3 --> 3 NaNO3 + Ag3PO4
In this reaction, we have the following ions:
Reactants:
Na3PO4:
- Dissociates into 3 Na+ ions and 1 PO4^3- ion
AgNO3:
- Dissociates into 1 Ag+ ion and 1 NO3- ion
Products:
NaNO3:
- Dissociates into 1 Na+ ion and 1 NO3- ion
Ag3PO4:
- Does not dissociate further since it is a solid
Based on this information, we can now write the ionic equation:
3 Ag+ (aq) + PO4^3- (aq) → Ag3PO4 (s)
B. (NH4)2SO4 + Ba(C2H3O2)2 + BaSO4
For this reaction, we have:
Reactants:
(NH4)2SO4:
- Dissociates into 2 NH4+ ions and 1 SO4^2- ion
Ba(C2H3O2)2:
- Dissociates into 1 Ba^2+ ion and 2 C2H3O2^- ions
Products:
BaSO4:
- Does not dissociate further since it is a solid
Based on this information, we can write the ionic equation:
Ba^2+ (aq) + SO4^2- (aq) → BaSO4 (s)
