प्रश्न
Give appropriate scientific reasons for the following statement:
During electrolysis of molten lead bromide, graphite anode is preferred to other electrodes.
उत्तर
In the electrolysis of molten lead bromide, reactive bromine is liberated at the anode. As bromine is very reactive, an inert electrode like graphite is preferred.
