Copper sulphate plus sodium hydroxide?
a big lump of mess i dont think so copper sulphate +sodium hydroxide = Na2So4 +Cu(OH)2 WHICH IS SODIUM SULPHATE AND COPPER HYDROXIDE
What happens when copper sulfate and sodium hydroxide are heated?
it starts changing to white because the colour of the copper sulphate solution becomes whote during the process of evaporation
What happens if you mix ferric sulphate and sodium hydroxide?
Solid ferric hydroxide, Fe(OH)3, precipitates out of solution. The resulting sodium sulphate remains dissolved.
What happens when Ferrous sulphate reacts with sodium hydroxide?
Sodium displaces the sulfate to make sodium sulfate; iron displaces the hydroxide to make ferrous hydroxide which becomes brown.
What are the products of iron II sulfate plus sodium hydroxide?
Iron Sulphate + Sodium Hydroxide -> Sodium Sulphate (Na2SO4) and Iron Hydroxide (Fe(OH)2)
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.
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.

Is there any colour change when sulfuric acid is mixed with sodium hydroxide?
Yes, when sulfuric acid is mixed with sodium hydroxide, a neutralization reaction occurs to form water and sodium sulfate. The color change that may occur will depend on the concentrations and purity of the substances being used. Generally, the reaction itself does not produce a noticeable color change.
Why does protein change colour when you add copper sulphate and sodium hydroxide?
The protein changes color because the copper ions in the copper sulfate solution bind to the peptide bonds in the protein molecules, forming a complex called biuret. When sodium hydroxide is added, the biuret complex changes color from blue to purple due to a chemical reaction that causes the copper ions to shift and absorb light differently, resulting in the color change.
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 is added to sodium hydroxide that will get sodium sulphate and water?
You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
What happens if you mix ferric sulphate and sodium hydroxide?
Solid ferric hydroxide, Fe(OH)3, precipitates out of solution. The resulting sodium sulphate remains dissolved.
Which acid and alkali make sodium sulphate?
Sodium sulfate is formed when sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH). This reaction results in sodium sulfate (Na2SO4) and water (H2O) as the products.
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.
