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. C12H22O11 ii. AgCl iii. AlBr3 iv. CH3(CH2) 3 CH3 v. CaCl2 vi. CH3 OH vii. C12H22O11 viii. KOH ix. HAc Complete the Data Table:
