titration curve

A titration curve is a graph that shows how the pH of a solution changes as an acid or base is gradually added to it. Initially, there may be only a slight change in pH, but as more of the substance is added, the pH changes rapidly, especially near the equivalence point, where the amount of acid and base are equal. This curve helps chemists understand the strength and behavior of acids and bases, and it visually indicates the point at which a reaction is complete, allowing for precise measurements of concentration.
