Hydration Number Matthew Brinkley and Taylor Thompson In this paper explaining the testing ground that my attendant (Taylor Thompson) and I did on December 12, 2011 we will be mensuration and discerning the the great unwashed in grams of many disparate 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 repress for Copper (II) Sulfate by heating the hydrate cat valium common salt to drive finish the water. The gamy hydrated salt turns to a flannel/ colorise anhydrous powderise. (CuSO4 times X H20 + heat) (CuSO4 + X H2O). Procedure: 1. Find the hole of the empty, clean, dry evaporating dish. 2. agree near 5 grams of the soft hydrated salt. 3. Find the green goddess of the blue salt + the dish. 4. Heat for some 10-15 minutes oer a low flame. Stir with the scoop, crushing the crystals, while safekeeping the di sh with tongs. 5. When the water has been driven off (turns to a white/grey) allow the dish to cool for about 5 minutes. 6. handling the dish with gloves, find the mass of the grey salt + the dish. 7. afterwards it has been cooled, place a small union of the grey anhydrous salt on a figure glass. Slowly add to start upher water from a wash bottle. recover visually and heart under the watch glass.

Data:| grass:| Type of substance| mess of empty crucible| 24.09 grams| | Mass of salt + crucible| 29.74 grams| Blue hydrated crystals| Mass of salt + crucible| 27.72 grams| pureness anhydrous powder| The work Taylor and I did to find the pith of blue hydra ted crystals, white anhydrous powder, and wa! ter that was in the experimentation 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 get a full essay, order it on our website: OrderEssay.net
