Inflection Point

Definition

An inflection point on a titration curve is where the curve changes from being concave up to concave down, or vice versa. It often corresponds to the equivalence point in a titration.

Concavity: In mathematics, this refers to how a curve bends. A curve is said to be concave up if it opens upwards like a cup and concave down if it opens downwards.

Second Derivative Test: A method used in calculus to determine whether a given stationary point is a maximum, minimum, or inflection point.

Equivalence Point:

As mentioned earlier, this is when exactly enough titrant has been added to react with all of the analyte (the substance being analyzed) in a chemical reaction.
