No such thing as KPO4, you are most likely thinking about potassium phosphate - but its formula is different.

Do you know solubility rules?

Sorry.  K3PO4.  Got it.  Anything but an alkali metal or ammonium ion will be insoluble with PO4.  Is that it??

Correct so far.

So, when you mix solutions of these salts, what should happen?
