Methodology:
$\ce{K2SO4}$ was added to 50 g of a soln saturated with ammonium phosphates or a suspension of proper overall composition. The equilibrium vessels were thermostated in an ice-water bath for 4 hrs. The equilibrium liquid phase was analyzed for $\ce{NH4^{+}}$, $\ce{PO4^{3-}}$ and $\ce{K^{+}}$ [1].
Sample Information:
