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 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 colour does argon go when an electrical current runs through it?
When an electric current is passed through Argon, it becomes blue
Why steel becomes a permanent magnet after electric current is passed through it?
When an electric current passes through steel, it creates a magnetic field within the steel. This magnetic field aligns the magnetic domains in the steel, causing it to become a permanent magnet. The alignment of the magnetic domains allows the steel to retain its magnetism even after the electric current is removed.
What is an electromanget?
An electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. The coil acts as a magnetic field when an electric current is passed through it, and becomes magnetic when the current flows. Electromagnets are used in a variety of applications, such as electric motors, MRI machines, and magnetic levitation trains.
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.
Does copper get heated when electric current is passed through?
yes it does
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
When an electric current is passed through a coil what does this create?
A magnetic field.
What happens when electric current passed through acidulated water?
e
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 source of heat does a halogen light use?
an electric current passed through it
What is a technique in which an electric current is passed through water to separate hydrogen from oxygen?
Electrolysis
What is the definition of eletro magnet?
A magnet that becomes energised when an electric current is passed through it.
How is chlorine extracted from the sea?
Chlorine is extracted from seawater using a process called electrolysis, where an electric current is passed through the saltwater to split it into its components. Chlorine is collected at the anode during this process.
Are all gases able to glow when electric current passed through them?
No, not all gases are able to glow when an electric current is passed through them. Gases must contain certain atoms or molecules that can emit specific wavelengths of light when energized by the electric current in a process called fluorescence or phosphorescence in order to produce a visible glow.
