WebJun 26, 2024 · The half-equivalence point is when just enough base is added for half of the acid to be converted to the conjugate base. When this happens, the concentration of H + ions equals the K a value of the acid. Take this one step further, pH = pK a . The second point is the higher equivalence point. WebSo pH of NaOH is higher than 7 and with addition of HCl, pH decreases of the solution.

Webadded. As can be seen below in the graph, the end point is reached when there is a sharp increase in the pH at 8.2 mL of NaOH added. The pH at half the equivalence point can be obtained from half of the volume at the equivalence point, which is at 4.1 mL of NaOH added. By extrapolation from the data points plotted in this WebA plot of pH vs volume is known as a titration curve. When the acid HA is titrated with NaOH, the reaction taking place is OH − (aq) + HA (aq) → A − (aq) + H 2 O (l) A polyprotic acid has more than one ionizable proton and each proton results in an equivalence point. As the titration proceeds, the nature of the solution will change.
