What is produced at the positive electrode for the electrolysis of copper sulfate?
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.
How could a sample gas be collected at the positive electrode when using electrolysis for copper?
To collect a sample gas at the positive electrode during electrolysis for copper, a gas collection tube can be placed directly above the positive electrode. As the electrolysis is carried out, the gas generated at the positive electrode will rise and move into the collection tube, allowing for easy sampling and analysis.
Why is hydrogen produced at the negative electrode and not sodium?
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.
What is the electrode at which chlorine is produced?
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.
What is produced when Sodium Chloride undergoes electrolysis?
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.
What is produced at the positive electrode of the electrolysis of molten lead bromide?
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.
What is produced at the positive electrode for the electrolysis of copper sulfate?
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.
What will happen when electric current pass through water?
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).

Name of one electrode and say is positive or negative?
The Cathode is the negative electrode; the anode is the positive electrode
Why chlorine gas forms at the positive electrode?
At the positive electrode electrons are removed from the solution. If chloride ions (Cl-) are present the will each lose and electron to form chlorine atoms, which then bond together to from Cl2 molecules, which is chlorine gas. Chlorine is extremely toxic, which is why you shouldn't use table salt (sodium chloride) as an electrolyte.
Stream of electrons produced at the negative electrode of a tube containing a gas at a low pressure?
cathode ray
What is the electrode at which chlorine is produced?
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 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 produced when Sodium Chloride undergoes electrolysis?
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.
What do you call a negative electrode?
Cathode- is the negative electrode.Anode- is the positive electrode.
