If sodium hydroxide solution and copper tetraoxosulphate were added to urine, a color change might occur. This reaction produces a blue color due to the formation of a complex between copper ions and proteins in urine. This test can be used to detect the presence of proteins in the urine.
The reaction between sodium hydroxide and copper sulfate will result in the formation of sodium sulfate and copper hydroxide. The products of this reaction will be a blue precipitate of copper hydroxide and a solution of sodium sulfate.
Copper hydroxide is considered a weak base because it only partially ionizes in water to release hydroxide ions. This results in a lower concentration of hydroxide ions in solution compared to strong bases. As a result, copper hydroxide has a lower ability to accept protons and is classified as a weak base.
When ammonia is added to a solution of copper sulfate, it forms a complex with the copper ions to produce a pale blue precipitate of copper hydroxide. The complex forms because ammonia acts as a ligand, coordinating with the copper ions to create a stable compound. This reaction is a result of the displacement of the sulfate ions by ammonia in the copper sulfate solution.
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
When aluminum is dipped into copper sulfate solution, a single displacement reaction occurs. The aluminum displaces copper in the solution, forming aluminum sulfate and copper metal. This reaction is spontaneous and the copper metal will begin to precipitate out of the solution.
The reaction between sodium hydroxide and copper sulfate will result in the formation of sodium sulfate and copper hydroxide. The products of this reaction will be a blue precipitate of copper hydroxide and a solution of sodium sulfate.
Solutions of copper (II) compounds will undergo precipitation reactions with sodium hydroxide solution when mixed together to produce a bright blue precipitate of copper (II) hydroxide and a solution of a sodium salt.The chemical equations for the reaction between Copper (II) nitrate and Sodium hydroxide are as follows:Cu(NO3)2 (aq) + 2NaOH (aq) → Cu(OH)2 (s) + 2NaNO3 (aq)Copper II nitrate + sodium hydroxide → copper II hydroxide + sodium nitrate

When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
When you mix copper sulfate and potassium hydroxide, a blue precipitate called copper hydroxide is formed. This is due to the reaction between copper ions from copper sulfate and hydroxide ions from potassium hydroxide. The chemical equation for this reaction is CuSO4 + 2KOH → Cu(OH)2 + K2SO4.
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.
When aluminum is dipped into copper sulfate solution, a single displacement reaction occurs. The aluminum displaces copper in the solution, forming aluminum sulfate and copper metal. This reaction is spontaneous and the copper metal will begin to precipitate out of the solution.
The pH of a 50% solution of sodium hydroxide (NaOH) and water would be around 13. Sodium hydroxide is a strong base, so when dissolved in water it will result in a highly alkaline solution with a high pH value.
When zinc granules are placed in a copper sulfate solution, zinc will undergo a displacement reaction with copper, displacing copper ions in the solution. This reaction will result in the formation of zinc sulfate solution and solid copper. The blue color of the copper sulfate solution will fade as the reaction proceeds.
This reaction is an example of a displacement reaction, where aluminum displaces copper from copper (II) nitrate solution to form aluminum nitrate and copper metal. The copper metal appearing on top of the solution is a result of this displacement reaction.
The ribbon starts to break up at the surface, a brown solid forms(copper metal), and the solution eventually becomes colourless (from losing copper ions)
