Titration curve worksheet: find the equivalence point

An example figure from the Titration Curve generator.

Titration curve of a weak acid with NaOH, with the equivalence and half-equivalence points marked by dots and blank lines for students to label — The titration of 20.0 mL of 0.150 M formic acid (HCOOH, pKa 3.75) with 0.120 M NaOH, graphed to 40 mL. The equivalence and half-equivalence points are marked with dots and dashed lines to the axes, each with a blank line for students to name it. Students can read the equivalence volume and the pKa off the graph.
