Copper sulphate plus sodium hydroxide?
When copper sulfate and sodium hydroxide are mixed, a blue precipitate of copper hydroxide is formed. This is because the hydroxide ions from sodium hydroxide react with the copper ions from copper sulfate to form the insoluble copper hydroxide. The net ionic equation for this reaction is Cu^2+ (aq) + 2OH^- (aq) → Cu(OH)2 (s).
What happens when copper sulfate and sodium hydroxide are heated?
When copper sulfate and sodium hydroxide are heated together, a series of chemical reactions occur. Initially, the copper sulfate decomposes to form copper oxide, water, and sulfur dioxide gas. Then, the copper oxide reacts with sodium hydroxide to form a blue precipitate of copper hydroxide.
Colour of sodium hydroxide of litmus?
Sodium hydroxide turns red litmus paper blue.
What is the action of sodium hydroxide on the colour of red litmus?
Sodium hydroxide is a strong base and will turn red litmus paper blue. This color change occurs due to the high concentration of hydroxide ions present in the sodium hydroxide solution, which react with the indicator dye in the litmus paper, causing the color change.
What are the products of iron II sulfate plus sodium hydroxide?
The products of the reaction between iron II sulfate and sodium hydroxide are iron II hydroxide and sodium sulfate. The balanced chemical equation for this reaction is FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4.
Copper sulphate add to sodium hydroxide result colour?
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 sulphuric acid is added to sodium bicarbonate why does the colour change?
this makes sodium sulphate and CO2
How many moles of sodium sulphate can be formed from two moles of sodium hydroxide?
No amount of sodium sulphate can be formed from sodium hydroxide alone, because sodium sulfate contains sulfur and sodium hydroxide does not. By neutralization with sulphuric acid, one formula unit of sodium sulphate can be formed from two moles of sodium hydroxide, according to the equation 2 NaOH + H2SO4 -> Na2SO4 + 2 H2O.
What happen if you add the copper sulphate to sodium hydroxide?
If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.
What are the two compounds formed when iron 2 sulphate is mixed with sodium hydroxide?
Iron (II) hydroxide and sodium sulfate are formed when iron (II) sulfate is mixed with sodium hydroxide. Iron (II) hydroxide is a green precipitate that forms in the reaction.
What is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
Copper sulphate plus sodium hydroxide?
When copper sulfate and sodium hydroxide are mixed, a blue precipitate of copper hydroxide is formed. This is because the hydroxide ions from sodium hydroxide react with the copper ions from copper sulfate to form the insoluble copper hydroxide. The net ionic equation for this reaction is Cu^2+ (aq) + 2OH^- (aq) → Cu(OH)2 (s).
What are the products of reaction between barium sulphate sodium hydroxide?

Where does the sodium sulphate go when copper sulphate mixes with sodium hydroxide?
Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
What is the product of sodium hydroxide plus copper sulphate?
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.
Is copper sulphate a reactant or a product in the following equation copper sulphate plus sodium hydroxide equals copper hydroxide plus sodium sulphate?
In the balanced equation CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4, copper sulfate (CuSO4) is a reactant. It reacts with sodium hydroxide (NaOH) to form copper hydroxide (Cu(OH)2) and sodium sulphate (Na2SO4).
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
