Write an equation for the thermal dehydration of copper (II) sulfate pentahydrate (CuSO4.5H2O) and for the...
When copper(II) sulfate (CuSO4) is prepared from copper(II) nitrate and sodium sulfate, the reaction initially produces a hydrated product, copper(II) sulfate pentahydrate (CuSO4.5H2O). If the CuSO4.5H2O is heated, the water is removed, leaving anhydrous CuSO4. What mass (in grams ) of anhydrous CuSO4 will be produced from 2.05 g of CuSO4.5H2O?
1. Calculate the mass of copper(II) sulfate pentahydrate (CuSO4.5H2O) needed to prepare 1.50 grams ol tetramminecopper (II) sulfate monohydrate (Cu(NH3)4] SO4 H2O according to the overall reaction on the first page of the lab. The overall net equation for the reaction is: Cu(H2O)2]SO4+H2O (aq) + 4 NH3 (aq) → [Cu(NH3)4]SO4+H2O + +4 H20 و اما الدم
A 2.794-g sample of a mixture of anhydrous copper(II) sulfate, CuSO4, and copper(II) sulfate pentahydrate, CuSO4∙5H2O,was analyzed by heating todrive off the water in the hydrate.CuSO4∙5H2O(s)→CuSO4(s)+ 5 H2O(g)If the mass after heating was 2.578 g, determine the percentage of the hydrate in the original sample
When copper(II) sulfate pentahydrate is heated in air above 100C, it loses the water molecules and also its blue color. CuSO4•5H2O—>CuSO4 + 5H2O If 9.75 g of CuSO4 are left after heating 15.25 g of the blue hydrate, calculate the number of moles of water originally present in 15.25 g of the hydrate.
12. If the student began with 83.2 g of copper(II) sulfate pentahydrate, CuSO4 . 5H20, how much Cu2l2 could be made? Note: The molecular weights of CuSO4· 5H20 and Cu212 are 249.5 g and 380.8 g, respectively.] A. 31.81g B. 63.5g C. 127 g D. 190 g
CuSO4• 5H20 -------> Custy + D u 2) What is the color for anhydrous salt of copper (II) sulfate (CuSO4)? What is the color for ionic hydrate compound of copper (II) sulfate pentahydrate (CuSO4.5H2O)? 3) How would you test a colorless crystalline compound to determine whether it is a hydrate or not? 4) How many grams of CuSO4.5H20 are needed to prepare 50.0 mL of a 1.00 M CuSO4 solution? 5) Suppose you used the Procedure in this experiment to...
S. (10 points) In the laboratory, you have available; solid crystals of copper (II) sulfate pentahydrate, lab balances, plenty of distilled water and access to all standard glassware. Explain with as much detail as you can, how you would prepare exactly 200.0 mL. of a 0.0600 M aqueous solution of copper (II) sulfate pentahydrate (CuSO 5H2O) 0.0600M ML 200.ML 11
An ore sample is known to contain copper sulfate pentahydrate, CuSO4•5H2O. If a 10.000 g sample of the ore loses 0.8332 g of water when strongly heated, what is the maximum quantity of CuSO4•5H2O that could be in the sample? (f.wt. CuSO4•5H2O = 249.69)
can someone help me please
F. copper sulfate pentahydrate see results Put a small amount of copper sulfate pentahydrate in a crucible and heat gently with a Bunsen bumer. When the reaction is complete, allow the crucible to cool (products) and then add a drop of water to the product. (products) 1. Complete and balance the equation. 2. Classify the reaction. 3. Write the equation for the reaction that occurs when a drop of water is added to products.
A blue compound called copper sulfate pentahydrate; the anhydrous form of this compound (copper sulfate) is white. Why? What causes the color change when water molecules are removed?
