A 1.00 L sample of saturated Ag₃PO₄ solution is allowed to evaporate at 25 degrees Celsius to a final volume of 500 mL. What is [Ag⁺] in the solution? Justify your answer.

I thought the [Ag⁺] would be doubled since the moles per liter of Ag₃PO₄ would have increased and therefore producing more of its products. However, I was told the answer was that the [Ag⁺] would remain the same in a saturated solution of Ag₃PO₄ since it is independent of the volume of the solution. I don't get this. Can someone please help me out? Thank you.

Solution was saturated! Concentration can't rise as it will have to get oversaturated.
