When copper sulphate reacts with iron what colour does it turn?
When copper sulphate reacts with iron, the solution turns blue due to the formation of copper ions in the solution. This is because copper is displaced from the copper sulfate and iron sulfate is formed, leading to the blue color of the solution.
What is the acid that reacts with copper 2 carbonate to give a blue solution?
The acid that reacts with copper(II) carbonate to give a blue solution is hydrochloric acid (HCl). This reaction forms a solution of copper(II) chloride, which appears blue due to the presence of copper ions.
Why does copper reacts with sodium chloride?
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
What is the chemical equation for copper chloride?
The chemical equation for copper chloride can be represented as CuCl2, where Cu is the symbol for copper and Cl is the symbol for chlorine. Copper chloride is formed when copper reacts with chlorine gas.
What forms when copper oxide reacts with sulfuric acid?
When copper oxide reacts with sulfuric acid, copper sulfate and water are formed. This chemical reaction can be represented by the equation: CuO + H2SO4 -> CuSO4 + H2O.
What is the word equation for the reaction between copper oxide and sulfuric acid?
Copper oxide reacts with sulfuric acid to form copper sulfate and water. The word equation is: Copper oxide + sulfuric acid → copper sulfate + water.
Copper plus oxygen is what?
copper oxide.......CuO
When copper chloride reacts with aluminum why does the color of the solution seem to fade?
When copper chloride reacts with aluminum, the aluminum replaces the copper in the compound through a single displacement reaction. The resulting compound formed, aluminum chloride, is colorless in solution. Therefore, the color of the solution appears to fade as the copper is displaced and the products of the reaction are colorless.
What happens when silicon reacts with copper chloride?
When silicon reacts with copper chloride, silicon will displace copper from the copper chloride solution to form silicon chloride and copper. The reaction can be represented as: 3CuCl2 + 2Si -> 2SiCl4 + 3Cu
What is observed when sodium sulphite solution is added to copper chloride solution?
When sodium sulfite solution is added to copper chloride solution, a white precipitate of copper sulfite forms. This precipitation reaction occurs because sodium sulfite reacts with copper chloride to form insoluble copper sulfite.
Write a word equation for the reaction that takes place in a copper oxide?
Copper oxide (CuO) reacts with hydrogen gas (H2) to form copper (Cu) and water (H2O). The word equation for this reaction is: copper oxide + hydrogen gas → copper + water.
Copper plus chlorine?
When copper reacts with chlorine, copper chloride is formed. The balanced chemical equation for the reaction is: 2 Cu + Cl₂ → 2 CuCl
