Electrochemical determination of acid-base and oxidation-reduction properties of concentrated phosphoric-acid solutions progressively neutralized by soda
Acid-base properties in 7 M H3PO4 medium neutralized by soda are characterized with an R(H) acidity function and R(H2PO4-), R(HPO42-), R(PO43-) basicity functions, which respectively represent the H+ activity in these media and their ability to donate H2PO4-, HPO42-, PO43- ions. The acidity level of...
