______

 In the 1sr blank below each container above, label each solution above as a strong, weak or non- electrolyte.  In the 2nd blank list the ions and their charges or just the molecule if no ions form. How to decide if a compound is a non-electrolyte, weak electrolyte, or strong electrolyte. Strong electrolytes

 Strong acids – HCl, HBr, HI, H2SO4, HNO3, HClO4, HClO3

 Strong bases – Group IA hydroxides, Ca(OH)2, Sr(OH)2, Ba(OH)2

 Soluble ionic compounds Weak electrolytes  weak acids  weak bases: any base not listed above Non-electrolytes  molecular compounds– bonding is covalent  Insoluble ionic compounds Ionic and covalent bonding Procedure: Virtual Lab; Go to the site www.conductivitylab.com Follow the instructions and determine if the light shines brightly or weakly for the following compounds. i.
