The pKa of dihydrogen phosphate (H2PO4−) is 7.21. If a pH 8.0 buffer is made from the protonated and de-protonated forms of H2PO4−, what is the ratio of the de-protonated to protonated form of H2PO4− at the buffer pH? The Henderson-Hasselbalch equation is pH = pKa + log (/). Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter the ratio in the box below.
