Acid-Base Titration Animation

In this animation, both the basic titrant and the acidic sample are clear and colorless. At first we see the titrant reacting with the hydrogen ions in the sample. The reaction produces water from acidic hydrogen ions and basic hydroxide ions. The product of this reaction, water, is clear and colorless, so no change takes place in the sample's appearance as the reaction progresses. When all of the available hydrogen ions in the sample have reacted with hydroxide ions from the buret, we are at the equivalence point. When any more base is added, it reacts with the indicator (HIN), the color change takes effect, and we are at the end point.
