WebIf you look at a titration curve of phosphate, you'll see a plateau around pH 7.2 ( the pKa of H2PO4-) . This means that at that pH, half the phosphate will exist as you added it, as H2PO4-, and half will exist as HPO4 2-, having acted as an acid and lost a proton. WebThe pH of the sample in the flask is initially 7.00 (as expected for pure water), but it drops very rapidly as HCl is added. Eventually the pH becomes constant at 0.70—a point well …
