What is the solubility equilibrium for Mn3(PO4)2?
Isn't it this..
Mn3(PO4)2 (s) --> 3Mn^+2 (aq) + 2PO4^-3
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
where  means solubility in moles/liter.
