What is the pH of Monosodium Phosphate Anhydrous in solution?
A 1% w/v aqueous solution of Monosodium Phosphate Anhydrous has a pH of approximately 4.2–4.6, making it an acidic buffer salt. It is used in combination with Disodium Phosphate to formulate precise phosphate buffer systems across the pH range of 5.8–8.0 for pharmaceutical and biological applications.
What is the difference between Monosodium, Disodium, and Trisodium Phosphate?
These are the three sodium salts of phosphoric acid. Monosodium Phosphate (NaH₂PO₄) is acidic (pH ~4.4). Disodium Phosphate (Na₂HPO₄) is mildly alkaline (pH ~9.0). Trisodium Phosphate (Na₃PO₄) is strongly alkaline (pH ~12). Combinations of mono and disodium are used to create buffered solutions at any desired intermediate pH.
Can MSP Anhydrous be used in bowel preparation formulations?
Yes. Oral Sodium Phosphate Solution (combining Monosodium Phosphate and Disodium Phosphate in water) is used as a bowel preparation laxative for colonoscopy. It is also available as an enema for constipation relief. Monosodium Phosphate is the acidic component that, combined with DSP, creates an osmotically active neutral solution.
Is Monosodium Phosphate Anhydrous used in food products in India?
Yes. Monosodium Phosphate is approved as a food additive (FSSAI INS 339i) for use as an emulsifier, buffer, and sequestrant in processed foods within specified limits. It is used in cheese processing, beverages, and baked goods as a leavening acid component.
