When dealing with buffer systems, we often use the acid reaction to determine the equilibrium and set up the ICE table. The most common experimental method used to study acid-base systems is titration, which studies the stoichiometric addition of the acid to a base solution or the base to an acid solution to determine the value of K, or K, The value of the pK, or pK, is essential to the understanding of the buffer system, where pK, = -log...

Adding a few drops of a strong acid to water will change the pH of the water significantly. However, adding the same amount of strong acid to a buffer solution doesn't alter the pH significantly. Explain what happens to the pH of the water when the acid is added and why the pH for the water and the buffer solution will be significantly different. DSC-Paragraph BLU-
