Part 6: What is the {eq}pH{/eq} at the equivalence point? Because HCl is a strong acid that is completely ionized in water, the initial [H +] is 0.10 M, and the initial pH is 1.00.Adding NaOH decreases the concentration of H + because of the neutralization reaction: OH − + H + ⇌ H 2 O (in part (a) in Figure 16.5.2).Thus the pH of the solution increases gradually. The Ka for formic acid is 1.8e-4. 0.1M Formic Acid solution is titrated against 0.1 M NaOH solution.What would be the difference in pH between 1/5 and 4/5 stages of neutralization of acid? I have asimilar question with a weak/strong acid mix being titrated with NaOH. '18. I aggree with Nizar - NaOH is a stronger base than HCOOH an acid (look at the corresponding pK values). Now do you see why we couldn't ignore the amount of formic acid that ionized? Although you normally run the acid from a burette into the alkali in a flask, you may need to know about the titration curve for adding it the other way around as well. Our experts can answer your tough homework and study questions. What does mean by 1/5 and 4/5 stages please give a details explanation. I suppose that low pH prevents the deprotonation of the molecules and, thus, enhances the resolution of the whole separation. Join ResearchGate to find the people and research you need to help your work. Thus the pH of a solution of a weak acid is greater than the pH of a solution of a strong acid of the same concentration. the ka formic acid is 1.8x10^-4.
