Determine the pH during the titration of 11.4 mL of 0.231 M nitric acid by 4.23x102 barium hydroxide at the following points: (1) Before the addition of any barium hydroxide (2) After the addition of 15.6 mL of barium hydroxide (3) At the equivalence point (4) After adding 39.2 mL of barium hydroxide

Consider a solution of a weak acid  being titrated with a solution of a strong base to beyond the equivalence point. Which of the following statements is incorrect?   a. The pH will increase intially and then change very little until the equivalence point is reached   b. Only a small percentage of the weak acid will react with the added base   c. The volume of the base solution required to reach the equivalence point can be less than, equal to, or more than the volume of the acid solution.   d. At the equivalence point, the solution will be basic   e. Beyond the equivalence point, the solution will be basic   f. None of the above   g. The pH of the solution in the tiration flask is affected by the total volume at any given point

theoretically, the equivalence point and end point of a titration should be the same. Describe four factors that could be responsible for the difference between these two in an actual titration

Determine the pH during the titration of 20.1 mL of 0.429 M hydrocyanic acid (Ka by 0.359 M KOH at the following points. (a) Before the addition of any KOH (b) After the addition of 5.40 mL of KOH (c) At the half-equivalence point (the titration midpoint) (d) At the equivalence point (e) After the addition of 36.0 mL of KOH = 4.0×10-10)
