Hf ka value
WebKa = [H +] [F –] / [HF] Ka = x 2 / 0.2 – x Ka = (1.32 X 10 -5) 2 / 0.2 – 1.32 X 10 -5 Ka = 8.69 X 10 -10 Thus, we can quickly determine the Ka value if the pH is known. Ka from pKa … 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 …
