Sodium phosphate is a generic term for a variety of salts of sodium (Na+) and phosphate (PO43−). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms. The hydrates are more common than the anhydrous forms.
Uses
Sodium phosphates have many applications in food and for water treatment. For example, sodium phosphates are often used as emulsifiers (as in processed cheese),thickening agents, and leavening agents for baked goods. They are also used to control pH of processed foods.They are also used in medicine for constipation and to prepare the bowel for medical procedures. Moreover, they are used in detergents for softening water, and as an efficient anti rust solution.

Structure of Sodium Phosphate
Sodium phosphate is an ionic compound and so exhibits an electrovalent chemical structure. The phosphate anion itself consists of a covalent structure.
Sodium atoms have a total of 11 electrons of which one is in its outermost shell as sodium is an alkali metal. Sodium readily expels the outermost electron to produce sodium cation. Three Na+ and one PO43- get attracted to each other using the electrostatic force of attraction and a sodium phosphate molecule is generated.
