What substance is left in the solution after electrolysis?
The substance left in the solution after electrolysis depends on the specific electrolyte used. For example, in the electrolysis of water, hydrogen gas and oxygen gas are typically produced. In the case of a salt solution, the cations and anions of the salt may be discharged at the electrodes.
Why is water not used in the electrolysis of copper permanganate solution?
Water is not used in the electrolysis of copper permanganate solution because water will compete as an electrolyte and interfere with the desired redox reactions happening at the electrodes. Using water as an electrolyte would form other byproducts instead of the intended products of the copper permanganate electrolysis. This could lead to inefficient and unpredictable results in the process.
How is sodium sulfate involved in the process of electrolysis?
Sodium sulfate is used as an electrolyte in the process of electrolysis. It helps conduct electricity and allows ions to move between the electrodes, facilitating the separation of elements during the electrolysis process.
Can mercury be used as electrolyte?
No, mercury is not typically used as an electrolyte because it is a metal at room temperature and does not readily dissolve in water or other solvents to conduct electricity. However, mercury can be used as an electrode or in some industrial processes involving electrolysis.
How can electrolysis used in making jewelry?
Electrolysis can be used in making jewelry for plating or coating metals. By immersing the jewelry piece in an electrolyte solution and passing an electric current through it, metal ions can be deposited onto the jewelry surface, creating a layer of a different metal. This process can enhance the appearance of the jewelry by providing a new color or finish.
What are the metal strips called that are placed in the copper compound solution during electrolysis?
The metal strips are called electrodes. The positive electrode is known as the anode, and the negative electrode is called the cathode. They are used to conduct electricity through the electrolyte solution to facilitate the electrolysis process.

what apparatus is used for electrolysis of substances?
The apparatus used for electrolysis typically includes an electrolytic cell, which consists of two electrodes (an anode and a cathode) immersed in an electrolyte solution. A direct current power source is connected to the electrodes to drive the electrochemical reactions. Additional components may include a beaker or container to hold the electrolyte and a stirring device to ensure uniformity in the solution.
What is the name of the apparatus used to electrolysis of water?
The apparatus used for electrolysis of water is called an electrolysis cell or electrolytic cell. It typically consists of two electrodes connected to a power source, a container of water containing an electrolyte, and a mechanism to collect the gases produced during electrolysis.
How can electrolysis be used to produce hydrogen?
Electrolysis can be used to produce hydrogen by passing an electric current through water, splitting it into hydrogen and oxygen gases. This process involves using an electrolyzer, which contains electrodes and an electrolyte solution, to separate the hydrogen and oxygen molecules.
Why isn't iron used as the electrodes in electrolysis?
Iron oxidizes too easily to be used in electrolysis.
What will affect the electrolysis of molten copper chloride?
Factors that can affect the electrolysis of molten copper chloride include the current applied, the concentration of copper ions in the electrolyte, the temperature of the electrolyte, and the composition of the electrodes used in the electrolysis process. Additionally, factors such as the purity of the copper chloride and the presence of impurities in the electrolyte can also impact the efficiency of the electrolysis process.
What is used as the anode in sodium chloride electrolysis?
For example titanium (electrolysis in water solution).
Why electrolysis sometimes yields different products from those predicted using electrochemical series?
Electrolysis may yield different products because factors such as concentration of electrolyte, pH of the solution, temperature, and type of electrodes used can influence the reaction. These factors can cause deviations from the predictions based solely on the standard electrode potentials in the electrochemical series. Additionally, side reactions or impurities in the electrolyte can also affect the final products obtained during electrolysis.
