Upon completion of this lesson, you should be able to: draw and interpret titration curves qualitatively and quantitatively for reactions involving: a strong acid and a strong base a strong acid and a weak base a strong base and a weak acid select, based on the nature of the species involved, an appropriate indicator for an acid-base titration determine qualitatively the nature of the equilibrium at the stoichiometric equivalence point when a strong acid is mixed with a a weak base or when a strong base is mixed with a weak acid.

Titration of: a Strong acid with a strong Base

Titration of a Strong base with a strong acid

Titration of a Weak acid with a strong base

Comparison of WA + SB and SA + SB

Complete the analysis of this titration curve (assuming a 0 Complete the analysis of this titration curve (assuming a 0.100 M sample): Is the titrant an acid or a base? Why? Is the sample an acid or a base? Why? How many equivalence points occur? Why? How many quantitative (stoichiometric) reactions have occurred? Why?

For each item: sketch and label titration curves for each titration. suggest an indicator that is suitable to detect of the equivalence point. 0.10 M hydrofluoric acid titrated with 0.10 M NaOH 0.10 M sodium cyanide titrated with 0.10 M HCl (Hint: write the net ionic equation for the reaction first.)
