Acid-base titrations are procedures used in chemistry to determine the concentration of an unknown acid or base solution by neutralizing them with each other until they reach equivalence point (where moles of acid equal moles of base).
A substance that changes color in response to a chemical change such as pH change during titrations.
pH Scale: A measure of acidity or alkalinity of water soluble substances.
End Point: The point in a titration where the reaction between the titrant and the analyte is complete, often marked by a color change.
