Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.
What else can I help you with?
What is the cupric sulfate flame color?
Cupric sulfate produces a blue-green flame color when burned.
Cupric sulfate formula?
Cupric or copper II sulfate is CuSO4
- What would happen to the anhydrous cupric sulfate if you added water to it?
Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.
What is left when cupric sulfate and Fe metal react?
When cupric sulfate and Fe metal react, Fe displaces Cu from the cupric sulfate solution, forming ferrous sulfate and copper metal. The reaction produces a reddish-brown precipitate of copper.
How many moles is 44.78g of cupric sulfate?
To find the number of moles, you need to divide the given mass (44.78g) by the molar mass of cupric sulfate. The molar mass of cupric sulfate (CuSO4) is approximately 159.61 g/mol. Therefore, 44.78g of cupric sulfate is approximately 0.28 moles.
What is the colour of soluble cupric salts?
Cupric sulfate and chloride are blue; also cupric carbonate is blue but not soluble in water.
What is the cupric sulfate flame color?
Cupric sulfate produces a blue-green flame color when burned.
Cupric sulfate formula?
Cupric or copper II sulfate is CuSO4
What is the synonym of copper sulfate?

How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
What color of cupric sulfate mix into the water?
Blue is the solution's color When blue CuSO4.5H2O (copper(II) sulfate pentahydrate) is dissolved, the solution turns blue. When white CuSO4 (anhydrous copper(II) sulfate) is dissolved, the solution turns also blue.
What is CuSO4.5H2O known as?
This is copper(II) pentahydrate or cupric sulfate or blue vitriol.
What color does cupric sulfate burn?
Cupric sulfate burns with a green flame.
- What would happen to the anhydrous cupric sulfate if you added water to it?
Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.
When black copper oxide is added to dilute sulphuric acid what colour is the soloution at the end?
Blue cupric sulfate solutionAdded:Chemical formulas:- CuO, Cu(II)-oxide, cupric oxide (monocopper oxide), black- Cu2O, Cu(I)-oxide, cuprous oxide (dicopper oxide), red- sulfuric acid, H2SO4CuO + H2SO4 --> CuSO4 + H2O , cupric sulfate, blue solutionCu2O (red) also reacts with dilute sulfuric acid forming CuSO4 by:Cu2O + 2 H2SO4 --> CuSO4 + H2O + H2, cupric sulfate, blue solution
What will happen if you heat cupric sulfate?
It will change its color. From blue it will become white. It will change its color. From blue it will become white.
What is left when cupric sulfate and Fe metal react?
When cupric sulfate and Fe metal react, Fe displaces Cu from the cupric sulfate solution, forming ferrous sulfate and copper metal. The reaction produces a reddish-brown precipitate of copper.
