Chapter 17 – Study Guide Be able to explain how the common-ion effect affects the pH of a solution both mathematically and in words Be able to explain what a buffer solution does and what it can be made from Be able to determine whether or not a given pair of chemicals could be used to make a buffer Be able to pick an appropriate set of chemicals to make a buffer of specified pH Be able to show, using chemical equations, how a buffer resists changes in pH when small amounts of acid or base are added Be able to calculate the pH of a specified buffer (given the composition) Be able to determine the quantities of components needed to make a buffer of specified pH Be able to explain why the titration of a weak acid by a strong base initially forms a buffer Be able to explain what is meant by Buffer Capacity Be able to explain why the equivalence point of a weak acid/strong base titration is > 7 while the eq. pt. for a strong acid/strong base = 7 Be able to work titration problems Given Table 17.1, be able to pick an appropriate indicator for a titration and explain why it will accurately designate the equivalence point of the titration Be able to determine molar solubility from Ksp values, and vice versa Be able to determine the concentration of ions in a solution of a slightly soluble salt Be able to explain whether a given situation (e.g. adding NaCl, adding an acid, etc.) would increase, decrease, or have no effect on, the solubility of a slightly soluble salt
