Document Summary
In a typical acid-base titration, a basic (or acidic) solution of unknown concentration reacts with an acidic (or basic) solution of known concentration. The known solution is slowly added to the unknown one, while the ph is monitored with either a ph meter or an indicator (a substance whose color depends on the ph) At the equivalence point- the point in the titration when the number of moles of base is stoichiometrically equal to the number of moles of acid- the titration is complete. A plot of the ph of the solution during a titration is a titration curve of ph curve. Calculating titration we begin by calculating the volume of base required to reach the equivalence point, and then we determine the ph at several points during the titration. The ph at the equivalence point of a strong acid- strong base titration is always 7. 00. At the equivalence point, the strong base has completely neutralized the strong acid.
