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.
The anode is the negative electrode. It produces hydrogen gas.
The part of a neon stroke that ignites the gas is called the electrode or electrode tip. This is the point where the electrical current passes through, causing the gas inside the tube to ionize and emit light.
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
Electrolysis of water occurs when an electric current is passed through water. This process breaks down the water molecule into hydrogen and oxygen gas at the electrode surfaces. The hydrogen gas is produced at the cathode, while the oxygen gas is produced at the anode.
At the positive electrode, oxygen gas was produced.

Hydrogen is produced at the negative electrode during electrolysis because it is less reactive than sodium. Sodium ions are more likely to undergo reactions at the positive electrode because they are more reactive and readily lose electrons to form sodium metal. Hydrogen ions are less reactive and instead gain electrons at the negative electrode to form hydrogen gas.
When electric current passes through water, electrolysis occurs, breaking down water into its constituent elements of hydrogen and oxygen gas. The hydrogen gas is produced at the cathode (negative electrode), while oxygen gas is produced at the anode (positive electrode).
At the positive electrode (anode) of the electrolysis of molten lead bromide, bromine gas is produced. This is because bromine ions are attracted to the positive electrode, where they are oxidized to form bromine gas.

At the positive electrode, which is called the anode, oxygen gas is produced when copper sulfate is electrolyzed. This is because copper ions are being oxidized to form copper oxide at the anode, along with the release of oxygen gas.
The anode is the negative electrode. It produces hydrogen gas.
Chlorine gas is produced at the anode during the electrolysis of aqueous sodium chloride (brine) solution. At the anode, chloride ions are oxidized to form chlorine gas.
When sodium chloride undergoes electrolysis, it decomposes into sodium metal and chlorine gas. Sodium ions are attracted to the negative electrode (cathode) where they gain electrons to form sodium metal. Chloride ions are attracted to the positive electrode (anode) where they lose electrons to form chlorine gas.
