About this document
Determining Hydrate Formulas in Lab by 0bearsbeetsbattlestargalactica is a document available to read on EtoBox.
The document describes an experiment to determine the chemical formula of an unknown copper chloride hydrate. Students will heat the hydrate to drive off water and determine the mass lost. They will then dissolve and filter the remaining solid, using aluminum to reduce copper ions and isolate copper by mass. Finally, students calculate the number of moles of each element and determine the formula as CuxCly·ZH2O based on molar ratios of the elements. The post-lab questions ask how an incomplete dehydration
