Copper sulfate is added after the acid is used up to test for any excess unreacted iron in a redox reaction. In the presence of excess iron, copper sulfate reacts with the iron to form a distinct blue color (copper precipitates as copper(I) oxide). This color change indicates the end point of the reaction, helping to determine when all the iron has been used up.
What else can I help you with?
Is copper sulfate an acid or alkali?
Copper sulfate is neither an acid nor an alkali. It is a salt compound typically used as a fungicide, herbicide, or pesticide.
What acid is used to make copper sulphate?
Sulfuric acid is commonly used to make copper sulfate by reacting it with copper oxide or copper carbonate. The reaction forms copper sulfate and water, with sulfuric acid providing the necessary protons for the reaction.
What do you get if you mix copper oxide and sulfuric acid?
water and copper(II)sulfate CuO + H2SO4 --> CuSO4 + H2O
Copper sulphate can be made using a reaction between copper oxide and an acid Which acid?
Sulfuric acid is commonly used to make copper sulfate through a reaction with copper oxide.
What happens when you add excess copper oxide to dilute sulphuric acid?
When excess copper oxide is added to dilute sulfuric acid, the excess copper oxide will react with the acid to form copper sulfate and water. The reaction will continue until all the copper oxide is used up. This is known as a limiting reactant situation, where one reactant is completely consumed before the other.
Insoluble base used to make copper sulfate?
Sodium hydroxide (NaOH) is an insoluble base that can be used to make copper sulfate. When sodium hydroxide is added to a solution of copper sulfate, a blue precipitate of copper hydroxide forms. This precipitate can be filtered and then reacted with sulfuric acid to produce copper sulfate.
Is copper sulfate an acid or alkali?

How does lead behave in copper sulphate?
When lead is added to copper sulfate solution, a displacement reaction occurs where lead displaces copper from the solution to form lead sulfate and copper metal. This reaction is driven by the relative reactivity of the metals, with lead being more reactive than copper. The solid lead sulfate formed can be observed as a precipitate in the solution.
Copper sulphate can be made using a reaction between copper oxide and an acid Which acid?
Sulfuric acid is commonly used to make copper sulfate through a reaction with copper oxide.
Why can iron be used to get copper from copper sulfate?
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
What happens when you add excess copper oxide to dilute sulphuric acid?
When excess copper oxide is added to dilute sulfuric acid, the excess copper oxide will react with the acid to form copper sulfate and water. The reaction will continue until all the copper oxide is used up. This is known as a limiting reactant situation, where one reactant is completely consumed before the other.
What salt do you make if you add copper carbonate to sulphuric acid?
If you add copper carbonate to sulphuric acid, you will form copper(II) sulfate, which is a salt that is commonly used in agricultural and chemical processes. This reaction also releases carbon dioxide gas as a byproduct.
What other else substances that can use instead of copper oxide in preparing copper sulphate?
Copper carbonate or copper hydroxide can be used as alternatives to copper oxide in preparing copper sulfate. These compounds can react with sulfuric acid to produce copper sulfate in a similar manner to copper oxide.
Can copper chloride react with sulfuric acid to produce blue salt solution?
Yes, when copper chloride reacts with sulfuric acid, it can produce a solution containing copper sulfate, which is a blue salt. This reaction is often used to prepare copper sulfate solutions for various applications.
What term is used to describe the mixing of copper sulphate and water?
The term used to describe the mixing of copper sulfate and water is "dissolving." When copper sulfate is added to water, it dissolves to form a homogeneous solution where the copper sulfate molecules are evenly distributed throughout the water.
