The point where the pH corresponds to a solution of the weak base (B) in water. … Webb14 aug. 2024 · 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 (Figure 17.4.2a ): OH − + H + − ⇀ ↽ − H 2O. Thus the pH of the solution increases gradually.

Webb2 maj 2015 · So you would first figure out what the pH at the equivalence point is. Then you would choose an indicator that changes color near that pH. Now, you can ask about the relationship of the pH of color change and the $\mathrm{p}K_\mathrm{a}$ of the indicator. I think my confusion is caused by the way I look at pKa of acid-base indicator.
