What happens when sodium hydroxide is added to copper sulfate?
The reaction between copper(Il) sulphate and sodium hydroxide solutions is a good place to start. If you slowly add one to the other while stirring, you will get a precipitate of copper(II) hydroxide, Cu(OH)2.
What type of reaction occurs between copper sulfate and sodium hydroxide solutions?
Type of Chemical Reaction: For this reaction we have a double replacement reaction. Balancing Strategies: To balance this reaction be sure to count all of the oxygen atoms on both sides of the equation. Note that the 2 in Cu(OH)2 applies to all of the atoms in the parentheses.
What is the Colour of copper hydroxide?
greenish blue
Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH)2. It is a pale greenish blue or bluish green solid.
What is the Colour of copper sulphate solution?
Answer: The solution of copper sulphate is blue .
What happens when calcium sulphate reacts with sodium hydroxide?
Observation when calcium sulphate react with sodium hydroxide and caso4 react with excess naoh. Observation when calcium sulphate react with ammonia hydroxide and caso4 react with excess nh4oh. Thus it forms white colour precipitate of calcium hydroxide. With excess ammonium hydroxide the precipitate gets dissolved.
What is copper hydroxide formula?
CuOH
Copper(I) hydroxide/Formula
What is the colour of copper sulphate after heating?
On heating, the colour of copper sulphate crystals changes from blue to white. There are water droplets on the walls of the boiling tube. On adding 2-3 drops of water white copper sulphate turns blue.
Which food item gives purple colour when two drops of copper sulphate solution and 10 drops of caustic soda is added to it?
Egg white, turns violet when two drops of copper sulphate and ten drops of caustic soda is added to it.
