How much heat is associated with the dissociation of a weak acid, NaHSO4 in water? HSO4^-+H20 >>> H3O^+ + SO4^2-? (not sure if this is a seperate part?) Is this dissociation exothermic or endothermic? Questions (regarding bomb calorimetry): 1. Why do we use slightly different amounts of acids (HCL and NaHSO4) from the amounts of base (NaOH)? 2. In what order should you mix the acid and base? Would you pour acid into base, or is the opposite true? Does it matter? 3. When should you start and stop monitoring the temperature? How will the initial and final temperatures be determined?
Beta-Dicarbonyl Compounds, There are two reason why the enols of beta-dicarbonyl compounds, such as pentane-2,4-dione are relatively stable.
