First is the dissolution of the crystalline structure of the solid. FT-IR measurements on the polymer solutions suggested that dissolution process of chitin in calcium chloride dihydrate saturated methanol related with interaction of calcium chloride-methanol-water complex with amide and primary hydroxyl group of chitin molecule. The process of dissolving salts involves two exchanges of energy. So the two others are just wrong, there is no HCl, I've done this my self in the lab, and if CaCl2 made HCl, it would make it useless in many instances. Xiaoqin WU, Shitang TONG, Baohong GUAN, Zhongbiao WU. The bonds of the lattice are broken and this requires energy.
