Question

When `CH_(3)COOCH_(3)+HCl` is titrated with `NaOH` then at neutral point the colour of phenopthalein becomes colourless form pink due to:
A. due to formation of `CH_(3)OH`
B. due to formation of `CH_(3)COOH` which act as a weak acid.
C. Phenolpthalein vaporizes.
D. due to presence of `HCl`

Answer 1

Correct Answer - B
`CH_(3)COOCH_(3)` `overset(H_(2)O)underset(H^(+))rarr` `CH_(3)COOH+CH_(3)OH`
`HCl+NaOH rarr NaCl+H_(2)O`
`CH_(3)COOH+NaOH rarr CH_(3)COONa`
