Interpretation Introduction
Interpretation: The titration curve of three different bases by
Concept introduction: The titration between an acid and base is used for the determination of an acid or a base by neutralizing the given acid or base with an acid or base of known concentration. When the moles of a standard solution becomes equal to the moles of unknown concentration solution then the equivalence point is reached.
