Hydration Number Matthew Brinkley and Taylor Thompson In this paper explaining the testing ground that my married person (Taylor Thompson) and I did on December 12, 2011 we will be meter and discerning the the great unwashed in grams of many unalike items which Mr. Hood has supplied us with. We befuddle to see how to work a burner and how to use various lab equipment tools. Purpose: Determine the hydration fall for Copper (II) Sulfate by heating the hydrate vulgar saltiness to drive finish the water. The gamy hydrated salt turns to a duster/ colorise anhydrous powderise. (CuSO4 times X H20 + heat) (CuSO4 + X H2O). Procedure: 1. Find the hole of the empty, clean, dry evaporating dish. 2. disc everyplace near 5 grams of the soft hydrated salt. 3. Find the circle of the blue salt + the dish. 4. Heat for some 10-15 minutes over a low flame. Stir with the scoop, crushing the crystals, while belongings the dish with to ngs. 5. When the water has been driven off (turns to a white/grey) allow the dish to cool for about 5 minutes. 6. manipulation the dish with gloves, find the mass of the grey salt + the dish. 7. after(prenominal) it has been cooled, place a small union of the grey anhydrous salt on a figure glass. Slowly score water from a wash bottle. recover visually and looking under the watch glass.

Data:| grass:| Type of totality| mess of empty melting pot| 24.09 grams| | Mass of salt + crucible| 29.74 grams| Blue hydrated crystals| Mass of salt + crucible| 27.72 grams| washrag anhydrous powder| The work Taylor and I did to find the make sense of blue hydrated crystals, white anhydrous powder, and water ! that was in the try out is shown below: (CuSO4 times X H20 + heat) (CuSO4 + X H2O). 29.74grams-24.09grams= 5.56 grams of blue hydrated crystals in the experiment 27.72grams-24.09grams= 3.63 grams of white anhydrous powder in the experiment 29.74grams-27.72grams= 2.02 grams of water in all of the experiment To find the amount of moles in the water, you would do:...If you want to charm a full essay, order it on our website: OrderEssay.net
