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 of the...

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...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
