Food grade Sodium Phosphate Monobasic Monohydrate CAS 10049-21-5

What are Sodium Phosphate Monobasic Monohydrate?

Sodium phosphate monobasic monohydrate , also known as sodium dihydrogen phosphate monohydrate , is an inorganic phosphate composed of sodium ions, dihydrogen phosphate ions, and one molecule of water of crystallization. It is a common phosphate substance found in food additives.

Its chemical formula is:

NaH₂PO₄⋅H₂O

in:

· Na+ and Na + represent sodium ions;

· H₂PO₄−H₂ PO₄− represents the dihydrogen phosphate ion;

· H2OH 2 O represents one molecule of water of crystallization.

In water, it can dissociate into:

NaH2PO4⋅H2O→Na++H2PO4−+H2O NaH 2 PO 4 ⋅H 2 O →Na + +H 2 PO 4− + H 2 O

Understanding from the name:

· Sodium indicates sodium;

· Phosphate means phosphate;

· Monobasic indicates a single base, which usually corresponds to dihydrogen phosphate;

· Monohydrate refers to a single hydrate.
