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.
Disodium hydrogen citrate syrup how to use?
This medicinal syrup contains disodium citrate (E331ii); use exactly as directed on the product label or by your clinician—typically measure the dose, dilute it in water, take after meals, and maintain good fluid intake.
Disodium hydrogen citrate how to use?
As a food additive (E331ii) it’s added by manufacturers to regulate acidity and emulsify (e.g., in processed cheese); as a medicine, take only per label or medical advice, usually diluted in water and taken after meals.
Disodium hydrogen citrate liquid how to use?
Follow the label: measure the dose, dilute in water, take after meals, and drink plenty of fluids; this differs from its use as a food additive (E331ii) in foods.
Disodium hydrogen citrate syrup for what purpose?
It’s used as a urinary alkalinizer to reduce urine acidity, easing burning urination and helping prevent uric-acid kidney stones; it does not treat infections.
Disodium hydrogen citrate syrup how many times?
Use only as directed on your product or by your clinician—many formulations are taken up to three times daily after meals, but do not exceed the labeled frequency and seek advice if symptoms persist or if you have kidney or sodium-restricted conditions.
