pH
pH
The negative logarithm of the hydrogen ion concentration (H+). It measures the acidity or alkalinity of a solution. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic.
Equivalence Point
Equivalence Point
The point where the moles of acid and base are equal in a titration. This is the point where the color change of an indicator is observed.
Indicator
Indicator
A substance used to signal the endpoint in a titration. It changes color depending on the pH of the solution.
