When lithium iodide (LiI) is dissolved in water, the solution becomes hotter. [ Hint: According to Hess’s Law, the overall enthalpy change upon solution formation is the sum of the changes in enthalpy for each step. Recall which two terms on the right hand side of the equation below combine to make the heat of hydration. ] Hsolution = Hsolute + Hsolvent + Hmixing a.) Is the dissolution of LiI endothermic or...
