1 Electrolysis of molten lead bromide is considered to be a redox reaction. During electrolysis of molten lead bromide lead gets oxidised and bromine gets reduced. Thus both oxidation and reduction occur simultaneously. So it is a redox reaction.
2 Copper is good conductor of electricity but is considered to benon-electrolyte. Ans. Copper being a metal contains free electrons and conduction of electricity is carried out by the movement of free electrons, but copper does not dissociate into ions and hence, is anon-electrolyte.
3 Acetic acid is a weak acid and has fewer number ions so conductivity isless whereas dilute Sulphuric acid is a strong acid has more number of ions and therefore its electrical conductivity is more. Electrolysis of molten lead bromide is considered to be a redox reaction.
