March 2‚ 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a
