To understand the products formed at the electrodes upon electrolysis of molten ICI (sodium chloride), we need to consider the process of electrolysis and the reactions occurring at the electrodes.
Electrolysis is a process in which an electric current is passed through an electrolyte (a substance that conducts electricity when dissolved in water or molten form) to bring about a chemical change. During electrolysis, positive ions migrate towards the negative electrode (cathode) and negative ions migrate towards the positive electrode (anode).
- At the cathode (negative electrode):
The positive ions are attracted to the cathode and gain electrons, leading to their reduction. In the case of molten ICI, the positive ions are sodium ions (Na+). Upon gaining electrons, sodium ions are reduced to form sodium metal (Na). Therefore, the product formed at the cathode is sodium metal.
- At the anode (positive electrode):
The negative ions are attracted to the anode and lose electrons, leading to their oxidation. In the case of molten ICI, the negative ions are chloride ions (Cl-). Upon losing electrons, chloride ions are oxidized to form chlorine gas (Cl2). Therefore, the product formed at the anode is chlorine gas.
Therefore, the correct options for the products formed at the electrodes upon electrolysis of molten ICI are:
a) I2 at cathode (incorrect): Since the positive ions are sodium ions (Na+), iodine (I2) is not formed at the cathode.
b) Cl2 at anode (correct): The negative ions, chloride ions (Cl-), are oxidized to form chlorine gas (Cl2) at the anode.
c) I2 and Cl2 at anode (correct): While chlorine gas (Cl2) is formed at the anode, iodine (I2) is not formed during the electrolysis of molten ICI.
d) Cl2 at cathode (incorrect): Chlorine gas (Cl2) is formed at the anode, not at the cathode.
Hence, the correct options are (b) Cl2 at anode and (c) I2 and Cl2 at anode.
