Purpose: The purpose of this experiment is to determine the formula for an ionic solid formed in a reaction and write the chemical equation for the reaction. Procedure: Refer to pages 32-33 of Laboratory Experiments in General Chemistry, Volume 1 by Judith Casey and Robert Tatz, Hayden McNeil Publishing, 2009-2010. Report Sheet: See attached report sheet Sample Calculations: None requested Report Questions: 2.The charge on the sulfate ion is 2-, SO 4 2- . The formula for a sulfate of thallium is TI 2 SO 4 . What is the charge on the thallium ion in this compound? Thallium and sulfate form a second compound, TI 2 (SO 4 ) 3 . What is the charge on the thallium ion in this compound? Name the two compounds unambiguously. TI 2 SO 4 - thallium charge on this ion would be 1+, and the name of this compound would be Thallium (I) sulfate.
