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.

Which of the following statements about oxalic acid is true? a.) It is very soluble in water even in cold temperatures due to its low mass and ability to hydrogen-bond. b.) It reacts with water to form carbon dioxide and water. c.) It is only soluble in cold water but will precipitate out in hot water. d.) It has a lower melting point than most carboxylic acids so it melts when the solution is heated and thus cannot recrystallize. Thank...
