Take a clean beaker (250 ml) and put the powdered sample of copper sulphate in it. You can boil the copper sulfate solution to recover your copper sulfate. Procedure 2 would give you 10 grams of solute in 100 mL of solution. Finally, turn off the burner and set the copper sulfate solution aside to cool. You are adding copper sulfate pentahydrate CuSO4•5H2O (blue) to water. Procedure 1 would give you 10 grams of solute in about 110 grams of solution (9%). Cu 2+ at the negative electrode, copper ions gain electrons and form copper atoms; This process is used industrially to purify copper. Copper sulfate is a chemical compound with the formula CuSO4 and can be made in a chemistry laboratory by reacting copper oxide with sulphuric acid. asked by Anonymous on December 9, 2012; Physics. Add distilled water and stir the contents gently with the help of a glass rod. Expansion of concrete mixes with increasing copper slag (CS) content subjected to a sodium sulphate solution. methods. Then, carefully add small pieces of copper oxide to the hot solution, stirring the mixture lightly for 30 seconds after each addition. Copper sulfate has many uses, from a fungicide and herbicide in agriculture, to creating the vivid blue colors in fireworks or for use in copper plating. Keep heating the solution for 1-2 minutes or until it looks cloudy with black powder. In order to make the solution more clear add two or three drops of concentrated sulphuric acid in it. Top Answer. You can boil the copper sulfate solution to recover your copper sulfate. Calculate the pH of a solution obtained by mixing 100cm3 of 0.1M HCl and 100cm3 of 0.2M NaOH .

Since you don't know the density, you can't calculate the percent. Dissolve separately 1 kg copper sulphate in 50 litres water and 1.25 kg washing soda (or 0.475 kg soda ash) in 50 litres water and slowly add the soda solution to the copper sulphate solution with stirring. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol. How to make copper sulphate (soluble salt) from an insoluble base (copper oxide) and sulphuric acid?
3. Adapted from Najimi et al. Add in excess copper(II) oxide. Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula Cu SO 4 (H 2 O) x, where x can range from 0 to 5.The pentahydrate (x = 5) is the most common form. The compound may be available in a hydrated form or at a different concentration or purity. Pour 25 cm 3 of sulfuric acid into a beaker.
