1)Does the solubility of borax in water increase or decrease as temperature increases?

Question

2)Is the solvation of borax in water an exothermic or endothermic process?

please help ive tried asking my ta but i cant understand him. he explains it through this weird process.

Answer 1

I think I would buy a box of Borax at the grocery (it is cheap), and experiment on both.
The second question really depends on the first answer. If the solubility increases with temperature increase, then it must be endothermic....
