Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation
