The functionality of orthophosphoric acid in the public water system

Stable concentration of orthophosphoric acid in the public water system.

A preferred acid is orthophosphoric acid used in an amount sufficient to establish a pH of about 0.6 to 4.

Monostarch phosphate is starch esterified with ortho-phosphoric acid, or sodium or potassium ortho-phosphate or sodium tripolyphosphate

Adjust the pH to 4,0 with orthophosphoric acid solution (3.3) and dilute to 1000 ml with water (3.11).

Monostarch phosphate is starch esterified with ortho-phosphoric acid, or sodium or potassium ortho-phosphate or sodium tripolyphosphate

One or more species selected from orthophosphoric acid, tripolyphosphoric acid, polymetaphosphoric acid, phosphorous acid, and sodium salts thereof can be used as the phosphate or phosphonate.

the following entries are inserted after the entry ‘sodium salts of orthophosphoric acid’:

Analytical method [1]For the determination of orthophosphoric acid in the feed additive: titration with sodium hydroxide (JECFA Monograph phosphoric acid [2]

Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound.

Said preparations also contain an alkaline salt or an ammonium salt of the orthophosphorous acid, and water and/or an aqueous solution.

The solution used is a solution of hydrochloric acid, either alone or in combination with orthophosphoric acid, and an acid-resistant foaming agent.

E338 Orthophosphoric Acid can cause irritation of skin and eyes.

The preferred phosphorus source is the orthophosphoric acid H3PO4, but its salts and esters, such as the ammonium phosphates, are also suitable.

Polyphosphoric acid, phosphorus(V) oxide and orthophosphoric acid, or a mixture of said compounds are preferably used as the liquid medium.
