The weak acid H3PO4has 3 ionizablehydrogens, with the pKas: 2.15, 6.82, 12.38
draw the titration curve for: H+ vs pH
you make a solution by adding 0.5moles of HPO42- and 0.1 moles of PO43- to 1 Liter of water
What is the pH of the solution? Is it a good buffer?
You add 0.3 moles of NaOH.
What is the new pH of the solution?
Is it still a good buffer?
