Popular questions
How are sodium phosphates made?
They’re produced by neutralizing food‑grade phosphoric acid with sodium hydroxide, carbonate, or bicarbonate to the desired ratio to yield mono-, di-, or trisodium phosphate, then crystallizing (often as hydrates); condensed polyphosphates are made by dehydrating/condensing orthophosphates at elevated temperatures.
How do saline enema sodium phosphates work?
They act as hyperosmotic salts that draw water into the colon, increasing volume and stimulating peristalsis to trigger a bowel movement; improper use can cause fluid and electrolyte imbalances, so they should be used only as directed.
How does sodium aluminate react with phosphates?
In water, sodium aluminate hydrolyzes to Al(OH)3, which binds phosphate and precipitates it as insoluble aluminum phosphate (AlPO4), especially near neutral pH—this is the basis for phosphate removal in water treatment.
How many meq of sodium does sodium phosphates have?
It depends on the specific salt and hydration: anhydrous NaH2PO4 ≈8.3 mEq Na per gram, Na2HPO4 ≈14.1 mEq/g, and Na3PO4 ≈18.3 mEq/g (hydrates contain less per gram); a typical adult sodium phosphate enema contains about 190 mEq of sodium.
How many sodium phosphates are there?
There are three main orthophosphate salts used in foods—monosodium, disodium, and trisodium phosphate—listed as E339(i–iii), plus various hydrates and condensed (polyphosphate) forms.
How much potassium gluconate should i take daily?
There’s no universal dose—use it only to meet your potassium needs and follow medical guidance. In the U.S., OTC tablets typically provide 99 mg elemental potassium (about 590–600 mg potassium gluconate); the adult AI for total potassium is ~2,600–3,400 mg/day from all sources.
Is potassium gluconate the same as potassium?
No—it's the potassium salt of gluconic acid that releases potassium ions in the body. By weight it’s about 16.7% elemental potassium, not pure potassium metal.
How much potassium gluconate per day?
Use only enough to meet your potassium requirement and as directed by your clinician. Common OTC servings provide 99 mg potassium (~590–600 mg potassium gluconate); excessive intake can be dangerous, especially with kidney disease or medicines that raise potassium.
Potassium gluconate para que sirve?
Como aditivo alimentario (E577) actúa como secuestrante y aporta potasio. Como suplemento, se usa como fuente de potasio para apoyar el equilibrio de electrolitos y la función muscular y nerviosa.
What is potassium gluconate good for?
As a food additive (E577) it’s used as a sequestrant and potassium source to help stabilize foods. As a supplement it provides potassium to support normal fluid balance, nerve transmission, and muscle function.
