Although the Ka values obtained for this experiment may be close to the values reported in the Gilbert textbook, the Kb values obtained for this experiment may CHEM 162 Lab Manual be appreciably smaller than the theoretical Kb values reported Gilbert. Describe at least three experimental errors that may be responsible for the lower experimental Kb values but have a smaller effect on the experiment Ka values. Do not include poor laboratory technique (e.g. unclean or contaminated glassware, not properly calibrating the pH meter, etc.) as possible sources of error.( Weak acids, weak bases and Salts lab)
