By passing electric current, ( NaClO ₃ ) is converted into ( NaClO ₄ ) according to the following equation ( NaClO ₃+ H ₂ O NaClO ₄+ H ₂ ) How many moles of ( NaClO ₄ ) will be formed when three Faradays of charge is passed through ( NaClO ₃ ) ?

Options

  1. A( 0.75 )
  2. B( 1.0 )
  3. C( 1.5 )
  4. D( 3.0 )

Correct answer

C. ( 1.5 )

Step-by-step solution

NaClO ₃+ H ₂ O NaClO ₄+ H ₂x=+5 Change in number of electrons =2 mole of NaClO ₃ required 2 ~F of charge to convert into 1 mole of NaClO ₄ 1 ~F will convert ^ 1 / 2 moles of NaClO ₃ into NaClO ₄ 3 ~F = 1 2 3 moles of NaClO ₄=1.5 mol.
