First Chem study guide after exam 3:   Buffer capacity: A buffer’s ability to resist pH change.  ­Higher concentrations of buffer components have higher capacities.  ­pH of a buffer is independent of its capacity, concentration is more important.   Buffer range: Range over which a buffer works effectively.  ­Most buffers have range of +/­ 1 pH.   How to prepare a buffer: Choose your conjugate acid­base pair.  ­Use the Henderson Hasselbach equation to calculate the ideal ratio between them. ­Use this ratio to calculate the amounts of each to mix together.  ­Mix the solutions….  Acid­Base titrations: A way to quantify a reaction.  ­Base is dropped into acid until color change to decide pH based on how much base was  needed.  ­Uses indicators, which are weak organic acids that respond to pH changes by changing  color.  ­Most indicators have a pH range of 2.   3 Types of titration curves may be made:  ­Strong acid + weak base = pH at equivalence point is less than 7.  ­Strong acid + strong base = pH at equivalence point is 7. ­Weak acid + strong base = pH at equivalence point is greater than 7.   We may now term formerly “insoluble salts” as slightly soluble. ­This salts experience very little dissociation before equilibrium is reached.   Solubility product constant (Ksp): Equilibrium for slightly soluble ionic compounds in  H2O.  ­Higher the Ksp, the more soluble the salt is.  ­Ksp shows how quickly equilibrium is reached based on amount of products that form  before it is reached.  ­Solid and pure liquid concentrations are still not considered when solving for Ksp.   O^2­ and S^2­ are very strong bases, so they automatically react with H2O.  ­Therefore, they will never exist in a solution alone.  ­Rather, they readily form SH­ or OH­ in solution.   S is used to compare solubility of salts regardless of how many ions are in each salt. ­Ksp may not do this. To compare Ksp the salts must have equal numbers of ions.   Solubility of ionic salts:  ­Does not change in the presence of a strong acid if the acid’s anion is present in the salt  as well.  ­Salts become more soluble in presence of a strong acid if they have an anion of a weak  acid though.  ­Adding a common ion may decrease the solubility of salts.
