Compare the pH values in the dilution experiment for each of the acids and bases used to the pH determined for distilled water. Do the pH values for the more dilute solutions approach the pH of the distilled water? What would you expect to happen if you continued to dilute these samples even further? Explain your answer.
the heat calculated after a calimetry experiment is equal to the enthalpy change for reaction. Use the thermochemical data to calculate the enthalpy chanfe for the reaction of NaOH and CH3COOH.
