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.
How do i mix sodium bisulphate to use as silver pickle?
Dissolve sodium bisulfate in water to about 5–10% by weight (roughly 50–100 g per liter), warm the solution to speed action, and always add the powder to water in a non‑metal container.
How much sodium bisulphate do you add to lower ph per 10,000 gallons of pool water?
As a rule of thumb, about 12 oz (≈340 g) of 93% sodium bisulfate lowers pH roughly 0.2–0.3 in 10,000 gallons; add with the pump running, then retest before dosing again per your product’s chart.
How much sodium bisulphate in 350 gal spa?
Start with about 1/2–1 teaspoon (≈2–5 g) of 93% sodium bisulfate to lower pH by ~0.2 in 350 gallons, circulate 20–30 minutes, and retest before repeating as needed per the label.
How much sodium bisulphate to add to lower ph in swimming pool water?
Typically 10–24 oz of 93% sodium bisulfate per 10,000 gallons lowers pH about 0.2–0.4, but the exact dose depends on current pH, total alkalinity, and product strength—dose in small increments with circulation and retest after 30–60 minutes.
How to make acetic acid from sodium sulphate?
You can’t practically make acetic acid from sodium sulfate/sodium bisulfate since they contain no acetate; if you need acetic acid, use vinegar (dilute acetic acid) or purchase acetic acid directly.
