Introduction

Sodium phosphate is a type of salt that is commonly used in various industries, including food, pharmaceuticals, and cosmetics. It is a crucial component in many products, and its correct formula is essential for understanding its properties and applications. In this article, we will explore the correct formula for sodium phosphate and discuss the different types of sodium phosphate compounds.

Understanding Sodium Phosphate

Sodium phosphate is a compound that consists of sodium (Na) and phosphate (PO4) ions. The phosphate ion is a polyatomic ion that consists of one phosphorus atom bonded to four oxygen atoms. Sodium phosphate can exist in various forms, including monobasic, dibasic, and tribasic.

The Correct Formula for Sodium Phosphate

The correct formula for sodium phosphate depends on the type of phosphate ion it contains. There are three main types of sodium phosphate compounds:

Monobasic Sodium Phosphate: This compound contains one phosphate ion (PO4) and one sodium ion (Na). The correct formula for monobasic sodium phosphate is NaPO4.
Dibasic Sodium Phosphate: This compound contains two phosphate ions (PO4) and two sodium ions (Na). The correct formula for dibasic sodium phosphate is Na2HPO4.
Tribasic Sodium Phosphate: This compound contains three phosphate ions (PO4) and three sodium ions (Na). The correct formula for tribasic sodium phosphate is Na3PO4.

Comparison of Options

Let's compare the three options given in the question:

Option A: NaPO4 - This is the correct formula for monobasic sodium phosphate.
Option B: Na(PO4)3 - This is not the correct formula for any type of sodium phosphate compound.
Option C: Na3PO4 - This is the correct formula for tribasic sodium phosphate.

Conclusion

In conclusion, the correct formula for sodium phosphate depends on the type of phosphate ion it contains. The correct formulas for monobasic, dibasic, and tribasic sodium phosphate are NaPO4, Na2HPO4, and Na3PO4, respectively. Therefore, the correct answer is C. Na3PO4.
