Potassium sulfate K2SO4 is a salt used as a fertiliser. Zinc phospate Zn3(PO4)2 is also a salt used as coating to prevent metal corrosion. Generraly speaking when you mix two salts toghether in aqueous solution they undergo a double replacement chemical reaction, this means that the both ionic metals formed in the solution exchange the ionic nonmetal parts. That is

3*K2SO4 + Zn3(PO4)2 = 2*K3(PO4) + 3*ZnSO4
