Given that NaOH exists as Na+ and OH- ions in solution, write down the equation for the reaction that occurs when the NaOH is dissolved in water. When 2.0 g of NaOH were dissolved in the 53.0 g water in a calorimeter at 24.00C, the temperature of the solution went up to 33.70C.
Using enthalpies of formation as given in thermodynamic tables, determine the ΔH for the reaction in the given equation.
