Learning Goal: To learn about titration types and how to calculate pH at different points of titration. In an acid-base titration, a titrant (solution of a base or acid) is added slowly to an analyte (solution of an acid or base). The titration is often monitored using a pH meter. A plot of pH as a function of the volume of titrant added is called a pH titration curve. Prior to the titration, the pH is determined by the concentration...

1. Calculate the volume (in mL) of the amount of 0.200 M NaOH required to neutralize a monoprotic weak acid solution made by 2.00 g of potassium hydrogen phthalate (KHP) dissolved in water. Hint: the complete neutralization occurs at the equivalence point, where the number of moles of the analyte (in this case, the weak acid) equal to the titrant (in this case, the strong base). 2. Identify the equivalence point, the half-equivalence point on the titration curve below and...
