Answer:

2PO_{4}^{-3} (aq) + 3Ca^{+2}(aq)-->Ca_{3}(PO_{4})_{2}(s)

Explanation:

In net ionic equation we remove the spectator ions. The ions which are present on both the side and are not forming any solid compound.

Let us write the balanced reaction first:

2Na_{3}PO_{4}(aq)+3CaCl_{2}(aq)-->3Ca_{3}(PO_{4})_{2}+6NaCl(aq)

The ionic reaction is:

6Na^{+}(aq)++6Cl^{-}(aq)+2PO_{4}^{-3} (aq) + 3Ca^{+2}(aq)-->Ca_{3}(PO_{4})_{2}(s)+6Na^{+}(aq)+6Cl^{-}(aq)

Thus net ionic reaction is

2PO_{4}^{-3} (aq) + 3Ca^{+2}(aq)-->Ca_{3}(PO_{4})_{2}(s)

I think the correct answer from the choices listed above is option D. The net ionic equation that will describe the reaction of the reactants when mixed is expressed as:

<span>2PO43–(aq) + 3Ca2+(aq) → Ca3(PO4)2(s)

Hope this answers the question. Have a nice day.

Suppose you have a mixture of solid mg(oh)2 and baso4, how do you separate the mixture
Step2247 [10]
This separation technique is a 4-step procedure. First, add H₂SO₄ to the solution. Because of common ion effect, BaSO₄ will not react, only Mg(OH)₂.

Mg(OH)₂ + H₂SO₄ → MgSO₄ + 2 H₂O

The aqueous solution will now contain MgSO₄ and BaSO₄. Unlike BaSO₄, MgSO₄ is soluble in water. So, you filter out the solution. You can set aside the BaSO₄ on the filter paper. To retrieve Mg(OH)₂, add NaOH.

MgSO₄ + 2 NaOH = Mg(OH)₂ + Na₂SO₄

Na₂SO₄ is soluble in water, while Mg(OH)₂ is not. Filter this solution again. The Mg(OH)₂ is retrieved in solid form on the filter paper.
