Copper Sulfate Lab Report - 773 Words | Bartleby From the masses of the water and anhydrous solid and the molar mass of the anhydrous solid (the formula of the anhydrous solid will be provided), the number of moles of water and moles of the anhydrous solid are calculated as shown below (\ref{4}, \ref{5}): \[n_{\ce{H2O}} = \frac{m_{\ce{H2O}}}{MM_{\ce{H2O}}} \label{4}\], \[n_{\text{Anhydrous Solid}} = \frac{m_{\text{Anhydrous Solid}}}{MM_{\text{Anhydrous Solid}}} \label{5}\]. Naming and Formulas: Simple Ionic and Covalent Compounds The name of this compound is "copper sulfate pentahydrate". 5: Properties of Hydrates (Experiment) - Chemistry LibreTexts Period: 5 4 fun activities! Academic Chemistry - Three paragraph conclusion. The techniques used in this lab are quantitative transfer and vacuum filtration with the reaction of 8.001 grams of copper (II) sulfate, CuSO4, and 2.0153 grams of iron powder, Fe. Our goal is to determine this value by comparing the moles of copper sulfate (anhydrate) to the moles of water. Calculate the change in mass for each sample. Conclusion The mass percent of water in copper sulfate pentahydrate is _______. Hydrate Lab. Next, an excess of aqueous barium chloride is added to the aqueous solution of the unknown salt. In an evaporating dish, gently heat a small amount (0.3 0.5 g) of \(\ce{CoCl2*6H2O}\) crystals until its color changes to violet then to blue. Solved Post-Lab Questions 1.
