The half‑equivalence point of a titration occurs half way to the
equivalence point, where half of the analyze has reacted to form
its conjugate, and the other half still remains unreacted.

Carry out a serial titration of one drop of the weak base 0.05 M NH, (aka NH,OH) with 0.01 M HCI. Stir. Measure the pH values of the solutions. Plot the titration curve on the same graph with your strong acid/strong base and weak acid/strong base titration curves. Compare with the computer-simulated curve (Figure 14.7). NOTE: Data from the computer calculation give an equivalence point pH of 5.70 at 5.0 drops of added 0.01 M HCI. Observations: Lane 1-purple (pH...

1.A. Suppose the weak diprotic acid, hydrogen sulfide (H2S), is titrated with KOH solution. What is the charge balance equation, representing all charged species present, once the titration is started? **I assumed it would be an acid balance with H2O as a biproduct but it still didn’t seem to get the correct score** please let me know how to properly solve this. 1.B An aqueous solution is formed by dissolving 0.20 moles of sodium sulfide (Na2SO3) in 1.0 L of...
