In what kind of cell are the redox reactions made to occur by an externally applied electrical current?
Redox reactions can occur in electrolytic cells when an externally applied electrical current drives non-spontaneous redox reactions to proceed. This is a process used in electrolysis, where an electrical current is passed through an electrolyte to induce chemical changes.
What happens when electric current is passed through acidified water?
When electric current is passed through acidified water (a mixture of water and an acid such as HCl), electrolysis occurs. The water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode. The overall reaction can be represented as: 2H2O(l) -> 2H2(g) + O2(g).
What type of chemical reaction takes place when a electric current is passed through water and write chemical equation for the same?
This is an electrolysis process:2 H2O-------------2 H2 + O2
When electric current is passed through water which gas is produced on cathode?
When electric current is passed through water, hydrogen gas is produced at the cathode. This is because water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) gases through electrolysis. The hydrogen gas is evolved at the negative electrode, which is the cathode.
What is electrolysis all about?
Is a method of using direct current DC) to drive an otherwise non spontaneous chemical reaction .It is highly important in the stage of separating elements from naturally occuring sources such as ores using an electrolytic cell
What are two important factors which control the process of electrolysis?
well two factors that affects electrolytic processes are, Quantity of electric current passed through the electrolyte and the nature of electrodes being used.
What is a technique in which an electric current is passed through water to separate hydrogen from oxygen?
Electrolysis
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
How do you strip hydrogen from water?
To strip hydrogen from water, a process called electrolysis is used. In electrolysis, an electric current is passed through water to split it into hydrogen and oxygen gases. The hydrogen gas is collected at the cathode while the oxygen gas is collected at the anode.
Which type of chemical reaction takes place when electric current is passed through water?
The process is called electrolysis, and it usually results in a decomposition reaction. For example, passing an electric current through water results in the reaction 2H2O --> 2H2 + O2.
In what kind of cell are the redox reactions made to occur by an externally applied electrical current?
Redox reactions can occur in electrolytic cells when an externally applied electrical current drives non-spontaneous redox reactions to proceed. This is a process used in electrolysis, where an electrical current is passed through an electrolyte to induce chemical changes.
Name given to solution which decompose when electricity is passed through them?
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What is used to separate hydrogen and oxygen?
Electrolysis, the passing of electric current through water will separate the water into oxygen and hydrogen molecules.
How is silver electrolysis done?
In silver electrolysis, a silver anode is immersed in a solution containing a silver salt. When an electric current is passed through the system, silver ions from the anode move to the cathode, where they gain electrons and deposit as solid silver. This process allows for the purification and extraction of silver from its ore.
How can hydrogen be added to water?
Hydrogen can be added to water through a process called electrolysis, where an electric current is passed through water to separate it into hydrogen and oxygen gases.
Which experiment Faraday did about clue of electron?
Faraday's experiment with electrolysis provided clues about the existence of electrons. He observed that when an electric current passed through an electrolyte solution, elements were deposited at the electrodes in specific ratios, indicating the presence of fundamental particles carrying electric charge.
