Popular questions
  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. What is the formula for phosphoric acid?

    H3PO4.

  1. What is monopotassium phosphate used for?

    In foods (E340i) it’s used as an acidity regulator/buffer, emulsifying and stabilizing salt, humectant and thickener, and as a source of potassium and phosphate.

  2. Is monopotassium phosphate an electrolyte?

    Yes—it's a salt that dissociates into potassium (K+) and phosphate ions in water, so it acts as an electrolyte and is used to adjust mineral content and pH.

  3. What does monopotassium phosphate do to the body?

    It provides potassium and phosphate: potassium supports nerve and muscle function and fluid balance, while phosphate supports energy metabolism (ATP) and bone; normal food levels are safe, but people with kidney disease should avoid excessive intake.

  4. What is potassium phosphate monobasic?

    It’s another name for monopotassium phosphate (KH2PO4), the monobasic salt of phosphoric acid approved as food additive E340i.

  5. Cannabis when to foliar feed with monopotassium phosphate?

    Growers typically apply it as a dilute foliar spray in early bloom or to correct P/K deficiencies, at lights-off or cooler times; avoid spraying buds or late flower to reduce residue and mold risk.
