Acid-Base Titration Curve

Titrate 25.0 mL of 0.100 M analyte with 0.100 M titrant. Slide the titrant volume to trace pH; the equivalence point and (for weak systems) the buffer region are marked.

● current point ● equivalence ▲ half-equiv (pH = pK_a)

System:

titrant added 0.0 mL

2.87

Try: choose Weak acid + strong base and set the volume to 12.5 mL (half-equivalence): pH equals the pK_a (4.74), the flattest, best-buffered point on the curve.
