When 5.12 g of NaOH were dissolved in 51.55 g water in a calorimeter at 24.5 C, the temperature of the solution went up to 49.8 C.
a. Calculate qH20.
b. Find delta H for the reaction as it occurred in the calorimeter.
c. Find delta H for the solution of 1.00 g NaOH in water.
d. Find delta H for the solution of 1 mole NaOH in water.
f. Given that NaOh exists as Na+ and OH_ ions in solution, write the equation for the reaction that occurs when NaOH is dissolved in water.
g. Given the following heats of formation, delta H f, in kJ per mole, as obtained from a table of deltaHf data, calculate the delta H for the reaction in part f. Compare your answer with the result you obtained in Part e.
