A 0.200g sample of benzonic acid, C(6)H(...

A 0.200g sample of benzonic acid, `C_(6)H_(5)COOH`, is titrated with a 0.120 M `Ba(OH)_(2)` solution. What volume of the `Ba(OH)_(2) ` solution is required to reach the equivalance point?
`{:("Substance","Molar mass"),(C_(6)H_(5)COOH,"122.1 g "mol^(-1)):}`

A

6.83 ml

B

13.2 ml

C

17.6 ml

D

35.2 ml

Text Solution

Verified by Experts

The correct Answer is:
A
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
