CHEM 101 Chapter Lab: ConducticityLabReport
Document Summary
In this experiment, we determined the differences between the ionic compounds and the molecular compounds from conductivity. By measuring the ability of an aqueous solution to carry an electric current to determine whether the solution is an ionic or molecular compound. Thus, breakdown the fragments into charged species called ions; these ions enable the solution to conduct the electricity. On the other hand, covalent compounds or molecular compounds can not conduct electricity when dissolved thus no conductivity can be measured. Conductivity can categorize compounds into 3 categories: strong electrolytes: completely breakdown the fragments thus high conductivity, weak electrolytes: doesn"t breakdown completely thus low conductivity, nonelectrolytes: dissolves but doesn"t break down the ions thus very little conductivity. This will be explained more in part b of the experiment. In part c of the experiment, we explore the differences between monatomic and polyatomic effects on the conductivity of the solution. In part a, we measured the conductivity of these solutions:
