What is the meaning of E338?
E338 (Phosphoric Acid) – Food Additive: Health Hazards (Skin) & Uses (Soda) Phosphoric acid, also known as orthophosphoric acid or E338, is a colorless, transparent, odorless liquid with a syrupy consistency (relative density of 1.70). It is produced from the mineral phosphorus, that is found naturally in the body and foods.
What is the pKa of phosphoric acid?
The pKa value measures the acidity of a solution based on how the hydrogen ions of the acid dissociate when added to an aqueous solution. Since phosphoric acid, represented by the molecular formula H3PO4, has three hydrogen atoms, it dissociates three times, into H 2 PO 4–, HPO 42- and PO 43-.
What is the IUPAC name for H3PO4?
Infobox references. Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with the chemical formula H3PO4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound.
