The purpose of this lab was to use the scientific method to identify an unknown solution‚ based on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative

Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves
