Question

Complete and balance the following equation. Then write it as a net ionic equation. K3PO4(aq) + MgCl2(aq)

Answer 1

do you recognize the type of reaction this is?

Answer 2

no

Answer 3

K3PO4 (aq) + MgCl2(aq) -> Mg3(PO4)2(s) + KCl (aq)

K+ PO4(3-) Mg2+ Cl- Mg2+ PO4(3-) K+ Cl-
K+ Cl- Mg2+ PO4(3-) K+ Cl-
K+ Mg2+ K+

You see, you need more Mg2+ ions in right side,
thus 3 for MgCl2
Then you have 6 Cl- ions, and 6 for KCl
Then you need to have 6 K+ on left, 2 for K3PO4
and 1 for Mg3PO4

In addition, you see you change ions and balance them.
But there are on less soluble in water, which precipitates,
that´s why (s) to magnesium phosphate.

Answer 4

thanks

Answer 5

@Gebooors was that completely balanced?

Answer 6

2 K3PO4 (aq) + 3 MgCl2 (aq) -> 1 Mg3(PO4)2 (s) + 6 KCl (aq)

Answer 7

how do i do the net ionic equation
