Question

What is the chemical formula for sodium phosphate?

Answer 1

Hint – In this question use the concept that the chemical formula for sodium is Na and Phosphate is PO. Take care of the number of ions of sodium and phosphate so as to maintain neutrality of the overall compound of sodium phosphate.

Complete answer:
Sodium phosphate naturally occurs in many foods. It's also added to foods to maintain freshness, alter texture, and achieve a variety of other effects. Sodium phosphate is considered safe by the FDA but should be avoided by certain people, including those with kidney disease.
And the chemical formula for sodium phosphate is $N{a_3}P{O_4}$.
So this is the required answer.

Note – The IUPAC name of sodium phosphate is Sodium dihydrogen phosphate, other names of it include monobasic sodium phosphate too. Sodium phosphate is a generic term for a variety of salts of sodium $(N{a^ + })$ and phosphate $\left( {P{O_4}^{3 - }} \right)$. Phosphate are also families or condensed anions including di, tri and tetra and phosphates. Most of these salts are known in both anhydrous (water-free) and hydrated form.
