Monosodium phosphate

Monosodium phosphate

0Monosodium phosphate (MSP), also known as Monobasic sodium phosphate and Sodium dihydrogen phosphate, is an inorganic compound with the chemical formula NaH2PO4. It is a white, crystalline solid that is highly soluble in water and is often used in food and industrial applications.

Chemical Properties

Monosodium phosphate is a salt that is produced by the neutralization of phosphoric acid with sodium hydroxide. It is a strong acid and a weak base, making it a useful buffer in many chemical reactions. It is also a reducing agent, meaning it can donate electrons to other substances in a chemical reaction.

Uses

Monosodium phosphate is used in a variety of applications. In the food industry, it is used as a leavening agent to help dough rise in baked goods. It is also used as a pH regulator to maintain the acidity or alkalinity of foods. In the industrial sector, it is used in the production of detergents and cleaning agents. It is also used in water treatment processes to prevent the formation of scale and corrosion.

Health Effects

Monosodium phosphate is generally considered safe for consumption in moderate amounts. However, excessive intake can lead to an imbalance of electrolytes in the body, leading to symptoms such as nausea, vomiting, and diarrhea. Long-term exposure can also lead to kidney damage.

Environmental Impact

While monosodium phosphate is not considered a significant environmental hazard, its production and use can contribute to water pollution if not properly managed. It can also contribute to the eutrophication of water bodies if released in large quantities.
