What colour are copper sulphate crystals?
very dark blue
What happens when ammonia solution is added to copper sulphate?
A precipitate is formed which has a light blue colour. After shaking, the precipitate re-dissolves forming a dark blue solution.
What is the colour of ferric sulphate solution?
Ferric sulphate solution is typically yellow in color, often ranging from pale yellow to dark amber depending on its concentration.
What color would copper II nitrate burn?
Copper nitrate is definitely a blue colour, even though copper (II) ions, Cu2+, generally produce blue-green solids and solutions.
What is the change in color in testing for the presence of protein in egg albumin using solution sodium hydroxide and copper sulfate?
Copper sulphate when mixed with a protein will turn purple if the amount of protein is sufficient enough in quantity to trigger the reaction. Planex1234 says; No offense but i think it is starch that turns dark blue - purple. Thetada says: the colour changes are arguably similar. Iodine solution goes blue/black in the presence of starch. The colour that sodium hydroxide / copper sulphate solution goes in the presence of protein is variously described as mauve / purple.
What will make copper tubing turn dark gray black?
Copper tubing can turn dark gray or black due to oxidation or corrosion. This process is natural and occurs when the copper reacts with elements in the environment, such as moisture, oxygen, or sulfur compounds. It can also be accelerated by exposure to certain chemicals or pollutants.
What happen when copper iii sulphate solution react with ammonia?
When copper(III) sulfate solution reacts with ammonia, a dark blue precipitate of copper(II) hydroxide is formed. This happens due to the displacement of the ammonia ligands by hydroxide ions in solution, resulting in the precipitation of copper(II) hydroxide. The reaction can be represented as CuSO4 + 2NH3 + 2H2O -> Cu(OH)2 + (NH4)2SO4.
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
Is the dark substance on copper after heating a new substance?
The darks substance is copper oxide, formed when the copper reacts with atmospheric oxygen.
What happens when EDTA is added to a solution of ammonia and copper sulphate?
When EDTA is added to a solution of ammonia and copper sulfate, it forms a complex with the copper ions, displacing ammonia from the solution. This results in the formation of a stable, water-soluble complex known as a copper-EDTA complex. The copper ions are effectively chelated by EDTA, which prevents them from reacting further.
