Question: 1) Find the pH of 0.0100 M sulfuric acid … WebNov 5, 2015 · Note that the pKa 1.69 is assuming H X + X X − and is taken at 1/2 of the N a X + O H X − used. Knowing that H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa value of 1.99. If you had an acid with two lower pKa values then you'd see two pH transitions in the titrations.

WebJan 30, 2024 · For acetic acid, HC 2 H 3 O 2, the K a value is 1.8 × 10 − 5. Calculate the concentration of H 3 O + in a 0.3 M solution of HC 2 H 3 O 2. Solution Step 1: The ICE Table Since we were given the initial concentration of HC 2 H 3 O 2 in the original equation, we can plug in that value into the Initial Concentration box of the ICE chart. WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base.
WebOct 18, 2007 · For the triprotic acid, phosphoric acid, H3PO4, there are Ka1, Ka2, and Ka3. And we know from the book that the value of Ka3 is too small, so we neglect the [H+] contribution from it. Normally, we encounter questions involving pH calculations of neutralization of a diprotic acid and a base, for example, H2SO4 and NaOH.
