The following questions relate to the acid-base neutralizationof HCl and NaOH
HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l)
a. A 25.00 mL sample of HCl is titrated with 0.1045 M NaOH usingphenolphthalein as an indicator. The buret containing NaOHinitially reads 0.30 mL and reads 48.29 mL at the end point.Determine the concentration of the HCl solution in mol/L. Show ALLwork.
b. If 50.0 mL of 0.500 M HCl at 25.0°C is added to 50.0 mL of0.500 M NaOH at 25.0°C in a coffee cup calorimeter, the temperatureof the mixture rises to 28.2°C. What is the heat of reaction permole of acid? (Assume the mixture has a specific heat capacity of4.18 J/(g·K) and that the densities of the reactant solutions areboth 1.00 g/mL). Show ALL work.
