Question

$100\, mL$ 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

• A. 112 mL
• B. 56 mL
• C. 224 mL
• D. 560 mL

Answer 1

Answer: (A)

112 mL

Answer 2

Acetic acid on electrolysis gives ethane as

Given moles of acetic acid,

$CH _{3} COOH =\frac{0.1 \times 100}{1000}=0.01$
$\because 2\, mol CH _{3} COOH$ gives $C _{2} H _{6}=22.4\, L$
$\therefore 0.01 \,mol CH _{3} COOH$ will give

$C _{2} H _{6}=\frac{22.4 \times 0.01}{2}$
$=0.112\, L$
$=112\, mL$
