How many coulombs of electricity is required to produce 1g of sodium metal by reduction of sodium ion?
संख्यात्मक
उत्तर
To calculate the coulombs of electricity required to produce 1g of sodium metal by the reduction of sodium ion, we use Faraday's Law of electrolysis.
\[\ce{Na^+ + e^- -> Na}\]
This shows that 1 mole of Na⁺ requires 1 mole of electrons (1 Faraday = 96,500 C).
Calculate Moles of Na in 1g
Molar mass of Na = 23 g/mol
Moles of Na in 1g = `1/23` = 0.0435 moles
Since 1 mole of Na requires 96,500 C, for 0.0435 moles:
Charge required = 0.0435 × 96,500
= 4,197.75 C
