Adding base to an acid barely moves the pH until you approach the equivalence point, where it leaps almost vertically. That steep jump is what makes an indicator color change so sharp. Educational tool.

Equivalence volume25.0 mL

pH at start1.00

pH at equivalence7.00

Governing equation

C_{a} V_{a} = C_{b} V_{e q} \Rightarrow V_{e q} = \frac{0.1 \times 25}{0.1} = 25.0 mL

Reading this result: Starting at pH 1.00, the curve stays flat until it leaps through pH 7 at the equivalence volume of 25.0 mL, where moles of base equal moles of acid.
