Popular questions
What is the formula for magnesium phosphate?
For the food additive E343(i) monomagnesium phosphate, the formula is Mg(H2PO4)2 (often found as hydrates); the fully basic “magnesium phosphate” is Mg3(PO4)2.
What does monobasic mean?
Monobasic means only one acidic hydrogen per acid unit is replaced by a metal; in phosphates it refers to dihydrogen phosphate salts (H2PO4−), such as Mg(H2PO4)2.
What is magnesium ascorbyl phosphate?
It’s a stabilized vitamin C (ascorbic acid) derivative used mainly in cosmetics and skincare; it is different from the food additive magnesium phosphates (E343).
What is the molar mass of magnesium phosphate?
Anhydrous monomagnesium phosphate, Mg(H2PO4)2, is about 218.28 g/mol; the tribasic magnesium phosphate Mg3(PO4)2 is about 262.86 g/mol (hydrate forms will differ).
Why boric acid is monobasic acid?
In water, boric acid B(OH)3 acts as a Lewis acid that accepts one OH− to form B(OH)4−, effectively releasing only one proton equivalent, so it is monobasic.
Girlsdoporn e452 who is she?
That appears unrelated to the food additive E452; E452 refers to polyphosphates, synthetic phosphate salts used in foods as emulsifiers, stabilizers, humectants, and sequestrants.
How does polyphosphates reduce affinity of hemoglobin for oxygen?
Inorganic polyphosphate can bind to positively charged sites on deoxyhemoglobin and stabilize the low‑affinity T-state, shifting the oxygen dissociation curve to the right and lowering O2 affinity. This is a biochemical interaction and not a typical food-use effect of E452.
How many states use polyphosphates?
There’s no official tally; polyphosphates are used by many water utilities across numerous U.S. states and worldwide for iron/manganese sequestration and scale/corrosion control, depending on local water chemistry.
How many states use polyphosphates to treat water?
No centralized count exists, but hundreds of U.S. community water systems in dozens of states use phosphate-based treatments (often polyphosphates or poly/ortho blends) for metal sequestration and corrosion control. Usage changes over time with source water and regulations.
How to remove polyphosphates from drinking water?
Effective options include reverse osmosis or nanofiltration, and strong‑base anion exchange; utilities may also use coagulation/precipitation with iron or alum followed by filtration. Polyphosphates hydrolyze to orthophosphate over time, which the same processes remove; activated carbon and boiling are generally ineffective.
