Titrated refers to the process of measuring the concentration or volume of a substance in a solution by adding another substance until a reaction occurs.
The equivalence point is the point in a titration where stoichiometrically equal amounts of reactants have been mixed. At this point, all the reactants have completely reacted with each other.
pH is a measure of acidity or alkalinity in aqueous solutions. It ranges from 0 to 14, with values below 7 indicating acidity, values above 7 indicating alkalinity, and a pH of 7 being neutral.
