Correct answer: Soluble substances combine to form a solid that is insoluble in the reaction solution. A precipitation reaction occurs when two solvated (usually aqueous) ions combine to form a solid precipitate.
What does it mean when all ions are spectator ions?
If all of the ions are spectator ions, that means there is no new compound forming and therefore no chemistry is occurring, so there is no chemical reaction.

Overview
Aluminium phosphate is a chemical compound. In nature it occurs as the mineral berlinite. Many synthetic forms of aluminium phosphate are known. They have framework structures similar to zeolites and some are used as catalysts, ion-exchangers or molecular sieves. Commercial aluminium phosphate gel is available.
Berlinite
AlPO4 is isoelectronic with Si2O4, silicon dioxide. Berlinite looks like quartz and has a structure that is similar to quartz with silicon replaced by Al and P. The AlO4 and PO4 tetrahedra alternate. Like quartz, AlPO4 exhibits chirality and piezoelectric properties. When heated, crystalline AlPO4 (berlinite) converts to tridymite and cristobalite forms, and this mirrors the behaviour of silicon dioxide.
Uses
There are many types of aluminium phosphate molecular sieves, generically known as "ALPOs". The first ones were reported in 1982. They all share the same chemical composition of AlPO4 and have framework structures with microporous cavities. The frameworks are made up of alternating AlO4 and PO4 tetrahedra. The denser cavity-less crystalline berlinite, shares the same alternating AlO4 and PO4 tetrahedra. The aluminophosphate framework structures vary one from another i…

AlPO4·2H2O dihydrate is found as the minerals variscite and meta-variscite. Aluminium phosphate dihydrate (variscite and meta-variscite) has a structure that can be regarded as an assembly of tetra- and octahedral units of phosphate anions, aluminium cations and water. Al ions are 6-coordinate and PO4 ions are 4-coordinate.
A synthetic hydrated form, AlPO4·1.5H2O is also known.
