How does a titration measure the concentration of a solution?
Quick Answer
Titration uses a solution of known concentration to react with an unknown one until the reaction is complete. The amount needed reveals the unknown concentration.
The Full Story
Titration is a standard analytical technique in chemistry. A measured volume of one solution is placed in a flask, and another solution of known concentration is added carefully until an endpoint is reached, often shown by an indicator color change or an electronic sensor. By using the balanced chemical equation and the volumes involved, chemists calculate the unknown concentration. This method is used for acids, bases, redox reactions, and more. It remains one of the clearest demonstrations of stoichiometry in practice.
