What is the net ionic equation for sodium phosphate and magnesium nitrate?

Answer 1

The net ionic equation for this reaction is:

3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)

How to get this answer:

To write the net ionic equation, you can start with the molecular equation:

2Na3PO4(aq) + 3Mg(NO3)2(aq) --> 6NaNO3(aq) + Mg3(PO4)2(s)

The molecular equation can be used to write the full ionic equation. To do this, you break down everything that is aqueous into its ionic constituents:

2Na+(aq) + 2PO43-(aq) + 3Mg2+(aq) + 6NO3-(aq) --> 6Na+(aq) + 6NO3-(aq) + Mg3(PO4)2(s)

You can then cross out whatever is the same on both side to get your net ionic equation:

3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)

Answer 2

3Mg(NO3)2 + 2K3(PO4) --> Mg3(PO4)2 + 6K(NO3)

Answer 3

The net ionic equation for sodium phosphate and magnesium nitrate is:

3Na^(+) + 2PO4^(3-) + 3Mg^(2+) + 2NO3^(-) -> 6NaNO3 + Mg3(PO4)2
