Phosphoric acid. H3PO4
We need 158,3 mL HrPO4 5M.
30 grams of H3PO4?
H3PO4 is phosphoric acid.
H3PO4 is a triprotic weak acid.
H3PO4 + 3NaOH --------> Na3PO4 + 3H2O
The conjugate base of H3PO4 is H2PO4.
The compound H3PO4 is called phosphoric acid.
The formula is H3PO4 O | HO-P-OH | OH O HO-P-OH H3PO4 OH
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
H3PO4 is a weak acid, and a weak acid is not sufficient for a buffer.
In H2O the conjugate base is H2PO4-, being conjugated to the acid H3PO4. As well: H3PO4 is conjugated acid to the base H2PO4-.
