Acid Base Equilibrium

Acid Base Equilibrium Test Outline

  • Acid base theories viz. all three definitions and examples
  • Identify an acid base reaction from a reaction, attribute it to one or more of the theories
  • Identify conjugate acid base pairs, identify Lewis acids and bases from examples
  • Difference between dilute and concentrated acids
  • Difference between strong and weak acids, bases, suitable examples needs to be known
  • Difference between and examples of polyprotic acids
  • Stage wise ionisation of polyprotic acids and equilibrium expressions for each step eg. Ka1, ka2 etc.
  • Dissociation constants like Kw, Ka, Kb. Relation between them, ability to write expressions representing them.
  • Percent ionization and how it can be used to determine pH of acidic solutions
  • Relation between pH, pOH, pKw, ability to convert [H+] to pH and vice versa
  • pH of acids, pH of bases, pH of buffers, Hendersen Hasslebach equations
  • Hydrolysis, predicting hydrolysis based on the presence of strong conjugate bases and strong conjugate acids
  • Titration problems, predicting pH of solutions obtained by mixing acids and bases, determining the limiting reagent and arriving at the pH of the resulting solutions.
  • Determination of pH of weak acids and bases using Ka and Kb
  • Ability to write Ka and Kb for hydrolysis of strong conjugate acids and strong conjugate bases pick an example for each and practice
  • How would you predict the pH change of a solution obtained, if the salt that is dissolved in water is capable of undergoing both acidic and basic hydrolysis?
  • Graphing, pH Vs Volume and prediction of equivalence point and end point for strong acid vs strong base, strong acid vs weak base, weak base vs strong acid.
  • Theories of indicators, how would your pick an indicator, rationale behind picking an indicator.
  • Difference Equivalence point and End point
  • Titration problems and different points of neutralizations
  • How would it be possible to determine Ka of weak acid from pH Vs Volume graph?
  • Buffers, definition, how to prepare acidic buffers, basic buffers, calculate pH of buffers, predicting masses of salts required to prepare a buffered solution of a specific pH.
  • What would be the criteria for picking a weak acid or base while preparing a buffer of a specific pH?
