Given below are two statements: Statement I : In the titration between strong acid and weak base methyl orange is suitable as an indicator. Statement II : For titration of acetic acid with NaOH phenolphthalein is not a suitable indicator. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. AStatement I is false but Statement II is true
  2. BBoth Statement I and Statement II are true
  3. CBoth Statement I and Statement II are false
  4. DStatement I is true but Statement II is false

Correct answer

D. Statement I is true but Statement II is false

Step-by-step solution

(1) MeOH is suitable indicator for titration of strong acid and weak base. (2) Acetic acid is weak acid and NaOH is strong base. Phenolphthalein is suitable indicator for titration of weak acid and strong base.
