My thought is that ,that when the electric current is passed through the electrolyte the aluminium from the anode gets attracted towards the cathode as it has positive charge & rest of the impurities get dissolved in electrolyte or get collected in the beaker.therefore,this way the anode decreases.

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 is the gas evolved at anode during electrolysis of aqueous NaCl?
Chlorine gas is evolved at the anode during the electrolysis of aqueous sodium chloride (NaCl) because chloride ions are oxidized to form chlorine gas.
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.
Why chloride ions are discharged at anode instead of hydroxide ions during the electrolysis of brine?
Chloride ions have a lower standard reduction potential than water, making them easier to oxidize at the anode compared to hydroxide ions. Therefore, chloride ions are preferentially discharged at the anode during the electrolysis of brine.
What type of electric charge does an aluminum electrolysis reaction need?
Aluminium metal is formed at the carbon anode (negative).

Chlorine gas is evolved at the anode during the electrolysis of aqueous sodium chloride (NaCl) because chloride ions are oxidized to form chlorine gas.
What kind of sign does anode has?
The anode has a positive sign. It is where oxidation occurs during electrolysis.

Why do aluminium factories had anode shops?
Aluminium factories have anode shops to produce, store, and maintain anodes used in the electrolytic process to produce aluminum. Anodes are necessary for the operation of electrolysis cells, which is the method used to extract aluminum from its ore. The anode shops also handle the recycling and replacement of anodes to ensure the continuous production of aluminum.
What will be the products on cathode and anode during electrolysis of the solution of magnesium sulphate?
At the cathode, magnesium metal will be produced, while at the anode, oxygen gas will be produced. This is because during the electrolysis of magnesium sulfate, magnesium ions will be reduced at the cathode to form magnesium metal, and water molecules will be oxidized at the anode to form oxygen gas and hydrogen ions.
During the separation of copper chloride what element is formed at the anode?
During the electrolysis of copper chloride, chlorine gas is formed at the anode. This is because chloride ions (Cl-) are attracted to the positive electrode (anode) and are oxidized to form chlorine gas.
How do you extract aluminium from Aluminium Oxide?
By Electrolysis. Aluminium is too reactive a metal and too high in the reactivity series to be reduced by carbon reduction. The method is to dissolve aluminium oxide in cryolite(a temperature reducing catalyst). An electrical charge is put across the mixture Whereupon the aluminium oxide forms the cation Al^(3+) and the oxygen forms the oxide anion (O^(2-) The aluminium cation moves to the cathode and received electrons from the electrical charge at the cathode to form aluminium metal. Correspondingly thre oxide anion moves to the anode and forms oxygen. However, because of the high electrical amperage , the anions if very hot , and made of carbon, so the oxygen reacts with the anode nnd forms carbon dioxide, which the released gas. Have a look and the Royal Society of Chemistry's video on this industrial process.
What products are formed during the electrolysis of sodium chloride solution?
At the anode, chlorine gas is formed (Cl2). At the cathode, sodium hydroxide (NaOH) and hydrogen gas (H2) are produced.
