During the electrolysis of molten sodium chloride, the time required to produce of chlorine gas using a current of is
55 minutes
110 minutes
220 minutes
330 minutes
The balanced chemical equation for the oxidation of chloride ions to chlorine gas at the anode is: This indicates that the formation of of gas requires the passage of of electrons, which corresponds to a charge of (). For producing of , the required charge () is: We know that charge , where is the current and is the time in seconds. Given current , To convert the time into minutes, we divide by : Since is closest to among the given options, is the appropriate answer.
