(Chemistry) (1) A method, or the process, of determining the strength of a solution, or the concentration of a substance in solution, in terms of the smallest amount of it required to bring about a given effect in reaction with another known solution or substance, as in the neutralization of an acid by a base. (2) A process whereby a solution of known strength (the Titrant) is added to a certain volume of treated sample containing an indicator. A color change shows when the reaction is complete (the end point).
