Answer: The number of faradays required is
Explanation:
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
The chemical equation for the reduction of niobium (V) ion to a neutral metal follows:
We know that:
Molar mass of niobium = 93 g/mol
We are given:
Mass of niobium (V) ion = 0.25 g
To calculate the amount of faradays required, we use unitary method:
For 93 g of niobium (V) ion, the amount of faradays required are 5 F
So, for 0.25 g of niobium (V) ion, the amount of faradays required will be =
Hence, the number of faradays required is
