Classic AP Requirement #16—Analytical Gravimetric Determination
In this laboratory, students determine the identity of a Group 1 metal carbonate by gravimetric analysis. The unknown is weighed, dissolved in water and precipitated as calcium carbonate. The precipitate is filtered, dried and weighed. From the data, the formula weight and the identity of the unknown metal carbonate are determined. Students gain valuable experience in the process of gravimetric analysis. The lab is free of heavy-metal waste typically generated with most gravimetric analysis labs.
Complete for a class of 24 students working in pairs.
