Add highlights, virtual manipulatives, and more. Use crucible tongs when cleaning the crucible with concentrated nitric acid. To achieve this, a known mass of hydrated salt was heated, evaporating the water (essentially distillation). Make sure that the tube is clamped near the bung as shown.

Excellent layout. \[ \underbrace{\ce{CuSO4*5H2O (s)}}_{\text{Deep Blue}} \ce{->[\Delta]} \underbrace{ \ce{CuSO4 (s)}}_{\text{Ashy White}} \ce{+ 5 H2O (g)} \label{1}\], \[ \underbrace{\ce{CuSO4 (s)}}_{\text{Ashy White}} \ce{->[\ce{H2O (l)} ]} \underbrace{ \ce{CuSO4 (aq)}}_{\text{Deep Blue}} \label{2}\]. Measure out between 1 and 4 grams of copper sulfate hydrate that you have crushed into the crucible. which works out to: You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in, In this lab a number of small experiments were conducted in order to observe the reactions of the materials tested. No trace of black, and indeed we dissolved the anhydrous salt in water (for growing some seed crystals later), and there was no insoluble residue. 5,7% of error in a Hydrated Crystal lab, is it too high? Chemicals: Copper (II) sulfate hydrateStudents will experimentally determine the percent composition of water in the copper (II) sulfate hydrate. Through the use of a vacuum filtration system the mass of Cu was, Flame Test Lab Report Purpose: To observe the difference between chemical and physical changes.
For this step, you are just changing your grams of water to moles using factor labeling. So now the final thing left to do is estimate how big $\Delta W_0$ and $\Delta W_e$ are. Heat the test tube and note any condensation that may appear at the mouth of the test tube as evidence of dehydration, note the color of the residue.

Embedded hyperlinks in a thesis or research paper. Is there any known 80-bit collision attack? AB1 All metal sulphate are soluble in water, except barium Bunsen Burner or Hot PlateComplete Lesson: PPT, Warm-up, Exit Ticket, Lab PaperStudents: drive off water of hydration calculate percent water use percent water and given elemental percentages to find formulaLab Contains: Student Lab Sheet Student Lab Make-up Sheet for Absent Students Student Lab Sheet with Answers in Italics Lab Quiz - Use as exit ticket, next day warm-up or quiz Lab Qui, This is a great lab to introduce or reinforce percent composition and empirical formulas. The formula for hydrated copper sulfate is: Possible improvements that could be made to this experiment in the future could include increasing the sample size, to produce a more average measurement. Finding the formula of hydrated copper(II) sulfate Be sure to subtract out the crucible before putting it into the proper space above.
