- What property of adipic acid is used in separation? a)solubility b)color c)melting point d)polarity
- How do you predict the solubility curve vs Temperature for adipic acid in water if im recrystallization from water? (Graph: x-axis is temperature and y-axis is solubility) How would the graph kinda look like?
