Purpose: To determine the type of bonding in some unknown substances using smallest number of tests. Materials: goggles 7 test tubes test tube rack test tube holder conductivity apparatus DI water stir rods scapulas well plate Bunsen burner dilute HCl Beaker plastic wash bottle marking pen 7 unknown substance conductivity meter Procedure: Step #1) Mark all seven test tubes from A through G. Step #2) Place your first unknown substance into the test tubes according to the letter that …showed first 75 words of 1142 total…

…showed last 75 words of 1142 total…that this substance was network solid which had covalent bond. Conclusion The purpose of this lab was to determine the type of bonding in some unknown substances using smallest number of tests. This lab taught us how to determine the physical properties of different bond types, ionic, covalent, and metallic, and to identify them by observing their properties with different various types of tests. We were successful on determining and identifying the substances' bond types.
