0.2 gm sample of benzoic acid `C_(6)H_(5)` COOH is titrated with 0.12 M `Ba(OH)_(2)` solution, what volume of `Ba(OH)_(2)` solution is required to reach the equivalent point ?

Options

A. 6.83 ml
B. 13.2 ml
C. 17.6 ml
D. 35.2 ml

Answer

A

Explanation

no of mole of Benzoic acid `= (0.2)/(122)`
eq. of Ba `(OH)_(2)=eq.of C_(6)H_(5)COOH`
`2x(0.12xxV)/(1000)rArr1xx(0.2)/(122)`
V=6.83ml
