Question

Total number of ions in aluminium phosphate:

Answer 1

When the number of atoms joined together to form a molecule, these molecules have less energy as compared to individual atoms. When an atom releases electrons and other atoms gain electrons then an ionic bond is formed.

Complete step by step answer:
Metals are electropositive in nature, it means metal having the capacity to lose the electrons. When metal loses the electrons they carry a positive charge. Non-Metals are electronegative in nature it means non-metal having the capacity to gain the electrons. When non-metal gains the electrons they carry a negative charge. Then attraction occurs between positive and negative charges and an ionic bond is formed and an ionic compound is formed.
When an ionic compound breaks it gives ions. So when aluminium phosphate$\left( {AlP{O_4}} \right)$ ionic compound breaks it gives two ions.
$AlP{O_4} \to A{l^{3 + }} + PO_4^{3 - }$

Additional information: Aluminium phosphate is white colour powder, crystalline in structure.
The molecular mass of Aluminium phosphate is $2.56g/c{m^3}$
The density of Aluminium phosphate is $121.9g/mol$
Aluminium phosphate is not soluble in water molecules because it does not form hydrogen bonds with water molecules so this compound is insoluble in water.

Note:
Aluminium phosphate is very useful for medical purposes, its tablet is used to regulate the B.P and it acts as an antacid in the stomachs of human beings.
Aluminium phosphate is used in making vaccines that are used to treat as enhance immunogenicity.
It occurs in nature as a mineral that is berlinite and the synthetic form is Aluminium phosphate is known.
It is used in two forms basically that is in liquid form and the gel form. Now it is used in cosmetics, dental cements, pharmaceuticals, paints and in the paper industry.
