What is the solubility equilibrium for Mn3(PO4)2?
Isn't it this..
Mn3(PO4)2 (s) --> 3Mn^+2 (aq) + 2PO4^-3
(aq)
but i keep getting it wrong. suggestions?
Mn+3(PO4)+2 (s) to be exact**
You wrote the solubility equation correctly (except the arrow, you should have <-->). But I suspect they want the expression to find the solubility constant, which would be
Ks= [Mn++]3[PO32]
where [] means solubility in moles/liter.

thank you!
The solubility equilibrium for Mn3(PO4)2 can be determined by considering the solubility product constant (Ksp), which describes the equilibrium between the solid compound and its dissolved ions in a saturated solution.
To write the correct equation for the solubility equilibrium of Mn3(PO4)2, you need to know the correct charges of the ions. Let's start by determining the charges of each ion in the compound:
- Mn3(PO4)2 is composed of 3 manganese (Mn) ions and 2 phosphate (PO4) ions.
- The charge of each phosphate ion (PO4^-3) is -3, as it is a polyatomic ion.
- To determine the charge of the manganese ions, we need to consider that the compound must be neutral overall. Since there are three manganese ions, the charge on each manganese ion must be +2/3 or +2.
Given this information, the correct solubility equilibrium equation for Mn3(PO4)2 can be written as:
Mn3(PO4)2 (s) ⇌ 3 Mn^+2 (aq) + 2 PO4^-3 (aq)
To verify the correctness of this equation, you can check if it satisfies the law of conservation of mass and charge. The total charge on the reactants' side (solid compound) should equal the total charge on the products' side (dissolved ions).
If you are still getting it wrong, ensure that you have balanced the charges correctly, considering the correct charges of each ion. Additionally, make sure you have accounted for all the ions involved in the dissociation of the compound.
Remember, correctly balancing charges and accurately writing solubility equilibrium equations can be challenging, so double-check your work and consult reliable reference materials if needed.
