Homework Answers
Correct answer is :-
C). it must be reasonably soluble.
To complete reaction with its acid standard must be completely soluble.
Other options are not fit in answer because of :-
- Most acid base reactions occurs on room temperature and it's not necessary that reaction must be exothermic.
- Standard should be monoprotic than polyprotic.
- It's not necessary that standard must have low melting point.
