Popular questions
Is phosphoric acid bad for you?
At permitted food levels it’s considered safe (GRAS in the U.S.; EFSA sets a group ADI for phosphates of 40 mg/kg bw/day as phosphorus). Overconsumption—especially via acidic soft drinks—can contribute to dental enamel erosion, and high phosphate intakes may be a concern for people with kidney disease.
Is phosphoric acid a strong acid?
No—it's a weak, triprotic acid (pKa ≈ 2.15, 7.2, 12.3), though concentrated solutions are corrosive.
What is phosphoric acid used for?
In foods it’s used as an acidulant to add tartness and control pH (e.g., in colas) and as a sequestrant/antioxidant to stabilize color and flavor.
What does phosphoric acid do to the body?
It dissociates into phosphate ions, which are essential for bones and energy metabolism, while the acid load is buffered and excreted. High intakes from acidic drinks can erode tooth enamel, and excess phosphate may be problematic in kidney disease or with low calcium intake.
What is the formula for phosphoric acid?
H3PO4.
What is the formula for magnesium phosphate?
For the food additive E343(i) monomagnesium phosphate, the formula is Mg(H2PO4)2 (often found as hydrates); the fully basic “magnesium phosphate” is Mg3(PO4)2.
What does monobasic mean?
Monobasic means only one acidic hydrogen per acid unit is replaced by a metal; in phosphates it refers to dihydrogen phosphate salts (H2PO4−), such as Mg(H2PO4)2.
What is magnesium ascorbyl phosphate?
It’s a stabilized vitamin C (ascorbic acid) derivative used mainly in cosmetics and skincare; it is different from the food additive magnesium phosphates (E343).
What is the molar mass of magnesium phosphate?
Anhydrous monomagnesium phosphate, Mg(H2PO4)2, is about 218.28 g/mol; the tribasic magnesium phosphate Mg3(PO4)2 is about 262.86 g/mol (hydrate forms will differ).
Why boric acid is monobasic acid?
In water, boric acid B(OH)3 acts as a Lewis acid that accepts one OH− to form B(OH)4−, effectively releasing only one proton equivalent, so it is monobasic.
