What gas is evolved dyring electrolysis of sodium acetate?
During the electrolysis of sodium acetate, the gas evolved at the anode is primarily carbon dioxide. This is a result of the oxidation of acetate ions present in the solution.
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.
Can Na be extracted from the electrolysis of its aqueous solution of Na-Cl?
Yes, sodium (Na) can be extracted from the electrolysis of its aqueous solution of sodium chloride (NaCl). During electrolysis, sodium ions are reduced at the cathode to form elemental sodium. Meanwhile, chloride ions are oxidized at the anode to produce chlorine gas.
Why electrolysis of concentrated aqueous sodium chloride liberate chlorine rather than oxygen at the anode?
During electrolysis of concentrated aqueous sodium chloride, chloride ions are preferentially oxidized over water molecules at the anode due to their higher standard electrode potential. This results in the liberation of chlorine gas instead of oxygen gas.
Can you use lead as an anode in electrolysis?
Lead can be used as an anode in electrolysis, but it may not be the most optimal choice due to its tendency to corrode and form lead oxide during the electrolysis process. This can affect the efficiency and longevity of the anode. Using materials like platinum or graphite for the anode may be more suitable for certain electrolysis applications.
What are the products of the electrolysis of aqueous lead nitrate?
At the cathode: lead metal is deposited At the anode: oxygen gas is evolved, nitrogen dioxide gas is evolved and lead ions are discharged to form lead nitrate

What kind of sign does anode has?
The anode has a positive sign. It is where oxidation occurs during electrolysis.
What are the products of the electrolysis of lead nitrate solution?
The products of the electrolysis of lead nitrate solution are lead metal deposited at the cathode and oxygen gas evolved at the anode. Nitrate ions will not participate in the reaction.
Which type of elements form at the anode?
At the anode, positive ions are typically formed or attracted towards it during electrolysis. These positive ions are usually cations, which are ions with a positive charge. The anode itself typically undergoes oxidation during the process.
What is electrolysis of sodium hydroxide?
It is the process of passing an electric current through aqueous sodium hydroxide so that hydrogen is produced at the cathode and oxygen at the anode.
How could a sample of gas be collected at the anode during-electrolysis of copper sulfate?
A sample of gas collected at the anode during the electrolysis of copper sulfate would likely be oxygen gas (O2) due to the oxidation of water at the anode. This would be because during this process, water is split into oxygen gas and protons, with the oxygen gas being produced at the anode.
What is the observation at the anode during electrolysis of concentrated potassium bromide?
At the anode during the electrolysis of concentrated potassium bromide, bromine gas is produced. This occurs because the bromide ions are oxidized to bromine atoms, which then combine to form bromine molecules.
