The electrolyte used in the Nickel-Iron (NiFe) accumulator is
dilute tetraoxosulphate(VI) acid
barium chloride solution
potassium hydroxide solution
sodium hydroxide solution
Correct answer is C
The electrolyte used in the Nickel-Iron (NiFe) accumulator is potassium hydroxide solution. It is a non-flammable, non-toxic, and relatively stable electrolyte. It is also a good conductor of electricity, which is important for the operation of the battery.
