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.
What is tetrapotassium pyrophosphate used for?
It’s used in foods as a sequestrant, stabilizer, and emulsifying salt to bind minerals, control pH, and improve water-holding and texture (e.g., in processed meats/seafood and processed cheese). It’s also used in toothpaste as an anti-tartar agent.
What are the chemical properties of tetrapotassium pyrophosphate?
It’s an inorganic salt (K4P2O7) with the pyrophosphate anion; a white, water‑soluble powder that forms alkaline solutions (about pH 10) and strongly chelates calcium and magnesium. It buffers pH, disperses proteins, and can hydrolyze to orthophosphate under acidic conditions or enzymatic action.
What are the dangers of tetrapotassium 1 - 10 pyrophosphate?
Within permitted food levels, phosphates including tetrapotassium pyrophosphate are considered safe; excessive phosphate or potassium intake may disrupt mineral balance and is a concern for people with kidney disease or on potassium‑restricted diets. Dust or concentrated solutions can irritate eyes, skin, and the respiratory tract due to alkalinity.
What are the dangers of tetrapotassium pyrophosphate?
At approved food-use levels it’s considered safe (phosphates have a group ADI from EFSA); high intakes of phosphates or potassium can affect calcium balance or pose risks for those with kidney disease or hyperkalemia. As a powder/solution it may cause eye, skin, or respiratory irritation.
What is tetrapotassium pyrophosphate in toothpaste?
It’s a tartar-control agent that chelates calcium to inhibit plaque from hardening into calculus, and it helps keep stains dispersed. It also contributes to pH control in the formulation.
