When copper sulphate solution is treated with less amount of ammonia solution bluish white precipitate of is formed?
copper hydroxide
When an aqueous solution of ammonia is added to the solution of copper (II) sulphate, a pale blue coloured precipitate of copper hydroxide is formed . this dissolves in the excess of the aqueous solution to give the deep blue colour solution containing the complex ion, tetraamminecopper (II).
What happen when copper sulphate solution is treated with ammonia solution?
When NH3 solution is added to CuSO4 solution drop by drop, ammonia ions completely react with copper sulphate and precipitates of copper hydroxide are formed. But when we add excess of ammonia, the precipitate dissolves and a soluble complex is formed.
When excess of liquid ammonia solution is added to copper sulphate solution the following observation is made?
When ammonium hydroxide is added to excess of copper sulphate solution a pale blue color of copper hydroxide is observed.
Why do copper sulphate crystals change colour from blue to white on heating due to?
Due to heating, the water of crystallization evaporates from the blue crystals of copper sulphate , and they develop white color.
When ferrous sulphate is treated with excess of ammonium hydroxide?

Why do copper sulphate crystals change its color from blue to white on heating due to hydration due to dehydrogenation due to dehydration due to hydrogenation?
Explanation: when copper sulphate is heated for some time, the blue colour disappears and it becomes white-gray in colour. This is because the water molecules are lost on heating and copper sulphate pentahydrate is converted to anhydrous copper sulphate.
When copper sulphate crystals are heated they lose their colour and turns white when water is added they restore their colour explain it with proper reason?
The copper sulphate crystals CuSO4. 5H2O contain 5 water molecules which are known as water of crystallization. When we heat the crystals, these water molecules are removed and the salt turns white. If we moisten the crystals again with water, the blue colour of the crystals reappear.
What happens when ammonia solution is added to copper sulphate?
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
Which compound is added first in excess of copper sulphate?
Ammonium hydroxide is added first in a small quantity and then in excess to a solution of copper sulphate. Which of the following observation can be made? Ammonium hydroxide is added first in a small quantity and then in excess to a solution of copper sulphate.
What is the colour of the copper ion in aqueous solution?
The copper ion in the aqueous solution of exists predominantly as [Cu(H 2O) 6] 2+. This complex ion imparts a characteristic pale blue color to the solution.
Which forms of copper sulfate are used in pesticides?
Copper sulfate pentahydrate and basic copper sulfate are the only copper sulfate forms contained in currently registered pesticide products. 3 Chemical properties for these two forms are summarized in the table below. The copper ion is the component of copper sulfate with toxicological implications.
