WebMar 29, 2024 · Reading pH at the y-axis, corresponding to V= 25 mL on the x-axis, gives us: ∴ pH = pKa = 4.7. Result: The pK a of the given acetic acid solution as per the above data is 4.7. Example # 3: The titration curve for the weak acid-strong base titration of propanoic acid (CH3CH2COOH) with 0.1 M NaOH is given below. WebWhat is pKa titration curve? ... How do you find the pKa value of acetic acid? The pKa of acetic acid is 4.76, which is the pH value at which half of the acid will be intact and the …
pKa = pH for strong acid - Chemistry Stack Exchange
WebOut of our three weak acids, hydrofluoric acid is the strongest, so it has the largest value for Ka, but notice it has the smallest value for the pKa. The lower the value for pKa, the more acidic your acid. 3.46 is lower than 4.74, and so hydrofluoric acid is more acidic than acetic acid. Up next: video. WebIt looks to be a little bit under 10, which matches with the actual pKa two value, which turns out to be 9.87. Finally, let's go back to the two equivalence points for our titration curve. … nsaids toxicity
