Answer 2

Option-(B).In the titration of weak acids, titrants used are only the methoxides of sodium.

Explanation:

• In the titration of a weak acid with a strong base, then the product formed will be the conjugate base of the weak acid.
• Its the $pH > 7$ at the equivalence point greater than 7. Therefore, the requirement would be an indicator that can change the pH range.
• When a weak acid titrant reacts with a weak base here the equivalence point of the solution will be basic
• If the base is stronger and acidic then the acid will also be stronger.
• If both are of equal in strength, then the equivalence point where pH will be neutral.
