Question 14 What is the pH at the equivalence point in a strong acid-weak base titration? -2 7 less than 7 16 greater than 7
Mark each of the following statements about the ½ equivalence point of an acid-base titration TRUE or FALSE. a. It is the point in the titration when the concentration of weak acid (HA) being titrated is equal to the concentration of the conjugate base (A− ). b. It is the point halfway between the beginning of the titration of a weak acid or weak base and the equivalence point. 2 c. When a strong acid is titrated with a strong...
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...
