i was hoping somebody else would noo arg!! my science teacher mss Edwards is asking me al these questions and i cant figure them out at all .. of well let me no guyz
love hollie x
Potassium bromide (KBr) is water soluble, when met with water it will dissolve. The dissolution of KBr in water is an endothermic reaction, the enthalpy change is about +19.8 Kj/mol.
Does anyone know why the solution process occurs even though the enthalpy is a relatively high positive number which should mean weaker bonds?

Bromine oxidizes iodide to iodine and is left as bromide.

∙ 13y agobecause it is an ionic bonds, and potassium is a metal that holds its electrons loosely, the potassium atom will give electrons over to the bromine.
