Is AlPO4 a precipitate?

Aluminum phosphate precipitate (AlPO4) is formed as a result: Al2(SO4)3 + Na3PO4 -> AlPO4 + Na2SO4. This is an example of a double displacement reaction.

What ions are present in AlPO4?

The formula for the aluminum cation is Al3+ , and the formula for the phosphate anion is PO43− . So the formula unit for aluminum phosphate represents a 1:1 ratio of aluminum and phosphate ions, which is represented as AlPO4 .

Is AlPO4 an antacid?

Is AlPO4 charge neutral?

a. The compound is not charge-neutral. b. Aluminum is a nonmetal so it cannot form an ionic compound.

What is wrong with the formula AlPO4?

A student wrote the formula for the compound aluminum phosphate as AlPO4 . What is wrong with this formula? Aluminum is a nonmetal so it cannot form an ionic compound. There cannot be three different atom types in a chemical formula.

What is an ALPO sieve?

There are many types of aluminium phosphate molecular sieves, gener ically known as "ALPOs". The first ones were reported in 1982. They all share the same chemical composition of AlPO 4 and have framework structures with microporous cavities. The frameworks are made up of alternating AlO 4 and PO 4 tetrahedra.

Is aluminium phosphate a compound?

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.

Is aluminum an adjuvant?

Aluminium adjuvant use is widespread due to their cheap price, long history of use, safety and efficiency with most antigens. It's unknown how such salts function as adjuvants. Similar to aluminum hydroxide, AlPO 4 is used as an antacid. It neutralizes stomach acid ( HCl) by forming AlCl 3 with it.

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…

Related compounds

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.
