What else can I help you with?
If you do electrolysis with copper electrodes in a solution of sodium carbonate what is the blue stuff left in the solution?
The blue substance left in the solution after electrolysis with copper electrodes in a sodium carbonate solution is likely copper(II) carbonate. This forms as a solid product of the reaction between the copper electrode and the carbonate ions present in the solution.
How is impure copper purified?
Impure copper can be purified through a process called electrolysis, where an electric current is passed through a copper sulfate solution, causing pure copper to be deposited on the cathode. The impurities are left behind as sludge or dissolve into the solution.
Why sulfuric acid added to water during electrolysis?
Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.
After electrolysis of brine solution what is the pH of that solution?
The pH of the solution after electrolysis of a brine solution will depend on the concentration of the resulting ions in the solution. The electrolysis of brine solution produces chlorine gas, hydrogen gas, and sodium hydroxide. The pH of the solution will increase due to the formation of sodium hydroxide, making it alkaline.
Breakdown of a substance by electricity?
Electrolysis is the process where an electric current is passed through a substance, causing it to break down into its component elements or ions. This process is commonly used in industry for purposes such as metal extraction and water purification. The substance being broken down is called the electrolyte, and the positive and negative electrodes are called the anode and cathode respectively.
Explain why a substance needs to be either in a solution or molten for electrolysis to work?
Because electrolysis needs a liquid to conduct the electricity.
If you do electrolysis with copper electrodes in a solution of sodium carbonate what is the blue stuff left in the solution?
The blue substance left in the solution after electrolysis with copper electrodes in a sodium carbonate solution is likely copper(II) carbonate. This forms as a solid product of the reaction between the copper electrode and the carbonate ions present in the solution.
Are there dangerous byproducts from electrolysis on a solution of calcium chloride and water?
Electrolysis of calcium chloride solution release chlorine.
What is the electrolysis of sodium chloride?
1. The products of the molten sodium chloride electrolysis are sodium and chlorine. 2. The products of the water solution of sodium chloride electrolysis are sodium hydroxide and hydrogen.
Why does a substance need to be a solution or molten for electrolysis to work?
For electrolysis to occur, a substance must be in a solution or molten state because this allows the ions to move freely. In solid form, the ions are fixed in place within a crystal lattice and cannot migrate to the electrodes. When dissolved in a solvent or melted, the ionic bonds break, enabling the ions to conduct electricity and participate in the electrochemical reactions at the electrodes. This movement of ions is essential for the process of electrolysis to effectively separate and produce elements or compounds.
What is used as the anode in sodium chloride electrolysis?
For example titanium (electrolysis in water solution).
Which substance is left behind after you evaporate sugar solution?
Sugar is 'left over' because it is nonvolatile
When a substance is decomposed by an electric current what type of reaction does it have?
This is electrolysis of a molten compound.
What is electrolysis Describe how this process can b used to differentiate between an element and a compound?
Electrolysis is a chemical process that uses electrical energy to drive a non-spontaneous reaction, typically involving the decomposition of a substance into its constituent elements. By applying an electric current to a compound dissolved in a solution or molten state, it can be broken down into its elemental components. If the substance produces distinct elements at the electrodes during electrolysis, it confirms that the original substance is a compound. In contrast, if no decomposition occurs and the substance remains unchanged, it indicates that the material is an element.
What does common salt break into during electrolysis of its solution?
The products of the electrolysis are sodium hydroxide and chlorine.
Which substance is manufactured by electrolysis?
Aluminium.
What chemicals can be obtained from the electrolysis of sodium chloride?
Electrolysis of a water solution: sodium hydroxide, hydrogen, chlorine..Electrolysis of molten NaCl: sodium, chlorine.
