A student performs a redox titration using an ORP sensor and calculates the second derivative of the titration curve. The resulting graph begins with negative values, increases steadily, crosses the x-axis at 15.4 mL of titrant added, and then continues to positive values. What is the significance of the volume corresponding to the x-axis crossing?
