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 delve into the world of sodium phosphate and identify the correct formula among the given options.

What is Sodium Phosphate?

Sodium phosphate is a chemical compound that consists of sodium (Na) and phosphate (PO4) ions. It is a type of salt that is formed when sodium ions combine with phosphate ions. Sodium phosphate is a white, crystalline solid that is highly soluble in water.

Chemical Formula of Sodium Phosphate

The chemical formula of sodium phosphate is a critical aspect of understanding its properties and applications. The correct formula is essential for identifying the compound and its reactions with other substances. In the given options, we have three possible formulas:

A. NaPO4: This formula suggests that one sodium ion (Na) combines with one phosphate ion (PO4).
B. Na(PO4)3: This formula indicates that one sodium ion (Na) combines with three phosphate ions (PO43-).
C. Na3PO4: This formula suggests that three sodium ions (Na3) combine with one phosphate ion (PO4).

Understanding the Chemical Formula

To determine the correct formula, we need to understand the chemical bonding between sodium and phosphate ions. Sodium ions (Na+) are highly reactive and tend to form ionic bonds with other ions. Phosphate ions (PO43-) are also highly reactive and can form ionic bonds with sodium ions.

Analyzing the Options

Let's analyze each option to determine the correct formula:

Option A: NaPO4: This formula suggests that one sodium ion combines with one phosphate ion. However, this is not a stable compound, as the phosphate ion has a -3 charge, and the sodium ion has a +1 charge. To form a stable compound, the sodium ion would need to combine with three phosphate ions.
Option B: Na(PO4)3: This formula indicates that one sodium ion combines with three phosphate ions. This is a stable compound, as the sodium ion has a +1 charge, and the three phosphate ions have a total charge of -3. This combination forms a stable ionic bond.
Option C: Na3PO4: This formula suggests that three sodium ions combine with one phosphate ion. However, this is not a stable compound, as the phosphate ion has a -3 charge, and the three sodium ions have a total charge of +3. This combination would result in a neutral compound, but it is not the most stable form of sodium phosphate.

Conclusion

Based on the analysis of the options, the correct formula for sodium phosphate is B. Na(PO4)3. This formula indicates that one sodium ion combines with three phosphate ions, forming a stable ionic bond. This compound is commonly used in various industries, including food, pharmaceuticals, and cosmetics.

Applications of Sodium Phosphate

Sodium phosphate is a versatile compound with a wide range of applications. Some of the most common uses of sodium phosphate include:

Food Industry: Sodium phosphate is used as a food additive to enhance the texture and flavor of food products.
Pharmaceutical Industry: Sodium phosphate is used as an excipient in pharmaceutical products to improve their stability and bioavailability.

Conclusion

In conclusion, the correct formula for sodium phosphate is B. Na(PO4)3. This compound is a stable ionic bond between one sodium ion and three phosphate ions. Its applications are diverse, and it is used in various industries, including food, pharmaceuticals, and cosmetics. Understanding the chemical formula of sodium phosphate is essential for identifying its properties and applications.
