Which of the following statements about oxalic acid is true?a.) It is very soluble in water even in cold temperatures due toits 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 inhot water.d.) It has a lower melting point than most carboxylic acids soit melts when the solution is heated and thus cannotrecrystallize.Thank...

2. While caffeine is very soluble in water, aspirin is only minimally soluble. a. Clearly explain why you think caffeine is soluble in water. b. In order to dissolve the aspirin, I had to use a sodium hydroxide solution (this is why you had to add HCl to the separatory funnel.) Clearly explain how the use of a sodium hydroxide solution allowed the aspirin to dissolve. Structures/reaction(s) will likely help your answer.
