Because in FeSO4, iron present in +2 oxidation state but the stable oxidation state is +3. The Fe(II) get oxidized into Fe(III) in ferrous sulfate solution that's why preparation of solution must necessary.
A red-brown colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution. This is due to the oxidation of ferrous ions in the solution to ferric ions, which results in the formation of ferric oxide/hydroxide on the surface of the zinc granules.
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
885x140=123900grams of copper sulphate per hour. If you are talking about using 885 gm of copper sulphate per ton of ore in the solution then the density of the copper sulphate(penta hydrate now because it's in water) is 2.284 gm per cm3 so that's 2.284x5=11.42gm per liter of solution, so 123900/11.42=10849.387 liters of copper sulphate(pentahydrate) per hour, NOTE:this is only how much copper sulphate is being used total in the solution which is 30% of the total liters used of solution because 25% of the water is inside the copper sulphate, the other 70% is just water. If you want the liters per hour of solution total, it is 34964.62 litres per hour of your 5% solution. I hope this was what you were looking for, I saw noone had answered and decided to try and get you what you needed.
You'll get first: blue Cu-sulfate pentahydrate crystall's and after further heating: white anhydrous Cu-sulfate powder.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Add some barium chloride solution to the neutral or weakly acid sulfate solution
A Benedict's solution is a solution of sodium citrate, sodium carbonate and copper sulphate, whose colour changes from blue to yellow to red in the presence of reducing sugars such as glucose.
A red-brown colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution. This is due to the oxidation of ferrous ions in the solution to ferric ions, which results in the formation of ferric oxide/hydroxide on the surface of the zinc granules.
Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.
A white precipitate of barium sulphate is formed when sodium sulphate solution is added to barium chloride solution. This is due to the formation of an insoluble salt, barium sulphate, which appears as a white solid in the solution.
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.

The aqueous solution of ferrous sulphate is typically pale green in color.
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
Hydrochloric acid is added to a solution being tested for sulphate ions to precipitate the sulphate as barium sulphate. This is a confirmatory test for the presence of sulphate ions in the solution because barium sulphate is insoluble and forms a white precipitate.
The solution is colorless.
