Kmieciak 1 Zachary Kmieciak Cassie and Tami TA: CH - Creating Copper Introduction: The purpose of this lab is to investigate what occurs when a solid substance, a metal carbonate, is added slowly to a solution of an acid. Also this should teach how to validate the proportionality of the amounts – volume and mass – that are required to accomplish this. Also this will help in making observations, designing procedures for a chemistry laboratory, recognize easily observable changes that signal a chemical reaction, and investigate proportional reasoning applied to mass and volume measurements. According to the law of conservation of mass Copper will neither be created nor destroyed in the reaction, so without any chemical error or human error there should be 100% of the copper in the solution in the end as added into the beginning.
