Ward's® AP Chemistry Investigation 6: Bonding: How are Solids Held Together?

Meets AP Science Practices 1, 4, 5, 6, and 7

In this lab, a series of tests will be performed in order to investigate the chemical and physical properties of known chemical compounds with ionic, covalent, or metallic bonding. Students will be required to make detailed observations and determine melting points in order to gather meaningful data and gain an understanding of these various types of chemical bonds. The information learned and gathered from these tests will ultimately be used to determine the bond type of unknown compounds. Includes sodium chloride, sodium bicarbonate, paraffin wax, benzoic acid, sucrose, aluminum solid, ethanol, hexanes, universal indicator, hydrochloric acid, and sodium hydroxide. Requires a conductivity meter, Melt-Temp, thermometer, and magnifying lens, available separately.
