Conductivity of Solutions of Ionic and Covalent Compounds
Purpose The purpose of this experiment was to use electrical conductivity on ionic, molecular acids, and covalent compounds in order to determine the properties of each compound.
Introduction
In chemistry, the term of an aqueous solution is defined as a substance that is soluble in water. For example, sodium chloride (NaCl) dissolves in water, or other known as table salt. In many cases when a substance is dissolved in water, it forms ions, an electrically charged atom. When this reaction occurs it is called an electrolyte at which the solution conducts electricity. The amount of the conductivity value will depend on the ability of the aqueous solution to conduct electricity. Strong electrolytes are solutes that exist either completely or nearly completely as ions, which results in a high conductivity value. As it is the opposite of a weak electrolyte were little electricity is conducted. In this laboratory experiment, multiple solutions will be analyzed by a conductivity probe to determine the conductivity value of each aqueous solution. The readings will appear on screen of the Power Macintosh, which includes Chemistry With Vernier and Logger Pro, this allows the experiment to be taken. For each compound being tested in this experiment, each will have a 0.05M concentration.
The hypothesis in this experiment is that Group A will have the highest amounts of conductivity, Group B will have the second highest amounts of conductivity, and Group C will have the very least.
Procedure For this laboratory experiment, goggles were obtained and then worn for cautionary needs. Then the preparation of the computer took place in order to monitor the conductivity. The file of the Experiment 13 folder was opened in Chemistry with Vernier. Which the Meter window was then displayed with live conductivity reading in the
