Write the net ionic equation for the reaction of calcium nitrate and sodium phosphate
I assume these are aqueous solutions.
First write and balance the molecular equation.
3Ca(NO3)2(aq) + 2Na3PO4(aq) ==> Ca3(PO4)2(s) + 6NaNO3
Then break these up into ions following these rules.
a. pure liquids are written as molecules.
b. gases are written as molecules
c. solids are written as molecules.
d. All others are written as ions.
3Ca^2+(aq) + 6NO3^-(aq) + 6Na^+(aq) + 2PO4^3-(aq) ==> Ca3(PO4)2(s) + 6Na^+(aq) + 6NO3^-(aq)
The above is the complete ionic equation. To change this to the net ionic equation, we cancel any ions that appear on both sides. So we can cancel 6Na^+(aq) and 6NO3^-(aq) which leaves us with
3Ca^2+(aq) + 2PO4^2-(aq) ==> Ca3(PO4)2(s)
Write a balanced net ionic equation for the reaction between calcium ions and sodium carbonate
Calcium nitrate + sodium _______ -> _______ hydroxide + _______
none
What type of Reaction is this? Not a redox because none of the oxidation numbers are changing, not an acid/base reaction... Any help here?
It probably won't help anymore but it's a double replacement reaction

this was almost perfect except the phosphate has a 3- charge not 2-
To write the net ionic equation for the reaction between calcium nitrate (Ca(NO3)2) and sodium phosphate (Na3PO4), we first need to determine the formulas of the compounds involved and the products they will form.
1. Determine the ions present in the compounds:
- Calcium nitrate (Ca(NO3)2) dissociates into calcium ions (Ca2+) and nitrate ions (NO3-).
- Sodium phosphate (Na3PO4) dissociates into sodium ions (Na+) and phosphate ions (PO43-).
2. Write the balanced chemical equation by swapping the ions between compounds:
Ca(NO3)2 + 3Na3PO4 -> 2CaPO4 + 6NaNO3
3. Determine the states of the compounds to write the complete ionic equation:
Ca(NO3)2(aq) + 3Na3PO4(aq) -> 2CaPO4(s) + 6NaNO3(aq)
4. Now, write the net ionic equation by eliminating the spectator ions (ions that do not participate directly in the reaction):
The spectator ions in this case are Na+ and NO3-. They appear unchanged on both sides of the equation.
Net ionic equation: Ca2+(aq) + PO43-(aq) -> CaPO4(s)
The net ionic equation represents the essential chemical change that occurs during the reaction and excludes the spectator ions, which do not participate in the reaction. It shows the formation of the insoluble calcium phosphate (CaPO4) precipitate.
