Answer
This statement is incorrect because a weak acid does not fully dissociate. Therefore, more volume of weak acid would be needed to reach the equivalence point.
Step 2
The weak acid will require a larger volume of base than the strong acid.

Answer
This statement is generally correct because weak acids are less effective at donating protons, necessitating a larger volume of base to achieve neutralization.
Step 3
The weak acid will require a smaller volume of base than the strong acid.

Answer
This statement is incorrect. A strong acid fully dissociates in solution, hence requiring less volume of base for neutralization.
Step 4
The volume of base required will depend on the molar mass of the acid used.

Answer
This statement is not typically correct for the context of titration, as the volume primarily depends on the concentration and strength of the acids involved rather than their molar masses.
