To determine the net ionic reaction and molecular equation for Ca3(PO4)2, we need to write out the chemical formula and then balance the equation.
The formula for calcium phosphate is Ca3(PO4)2. This means that one calcium ion (Ca2+) combines with two phosphate ions (PO43-) to form the compound.
To write the molecular equation, we can show the reactants and products:
Ca3(PO4)2 → 3Ca2+ + 2(PO43-)
Now, let's balance the equation:
3Ca3(PO4)2 → 9Ca2+ + 6(PO43-)
We have balanced the equation, but to determine the net ionic reaction, we need to identify the spectator ions. These are ions that do not participate in the reaction and are found on both sides of the equation in the same form. In this case, the Ca2+ ions are found on both sides of the equation, so they are spectator ions.
Therefore, the net ionic reaction is:
3(PO43-) → 6(PO43-)
In summary, the molecular equation for Ca3(PO4)2 is:
3Ca3(PO4)2 → 9Ca2+ + 6(PO43-)
And the net ionic reaction is:
3(PO43-) → 6(PO43-)
