100 ~mL of 0.1 M acetic acid is completely neutralized using a standard solution of NaOH . The volume of ethane obtained at STP after the complete electrolysis of the resulting solution is

Options

  1. A56 ~mL .
  2. B224 ~mL
  3. C560 ~mL
  4. D112 ~mL .

Correct answer

D. 112 ~mL .

Step-by-step solution

Acetic acid on electrolysis gives ethane as Given moles of acetic acid, CH ₃ COOH = 0.1 100 1000 =0.01 2 ~mol CH ₃ COOH gives C ₂ H ₆=22.4 ~L 0.01 ~mol CH CHOH ₃ COOH give aligned C ₂ H ₆ &= 22.4 0.01 2 &=0.112 ~L &=112 ~mL aligned
