Lab Activity
THERMOMETRIC TITRATION


AIM: The purpose of this experiment is to determine the concentration of hydrochloric acid, HCL by thermometric titration, and having done that, to calculate the enthalpy change for the reaction followed by the enthalpy change of neutralization.

PROCEDURE

  1. Using pipette and filter, transfer 50.0 cm³ of NaOH solution into the polystyrene cup. Allow to stand for a few minutes and then record the temperature of the solution.
  2. From a burette, 5.0cm³ of HCL to the cup
  3. Stir the mixture with the thermometer and record the temperature.
  4. Repeat step 2 and 3.
  5. Add successive 1.0 cm³ portions of HCL solution stirring the mixture and recording its temperature after each addition until complete 30 cm³.
  6. Add 3 successive 5.0 cm³ portions of HCL solution stirring the mixture and recording its temperature after each additional complete 45 cm³.
  7. Record your results in a suitable way. Analyze the results to find the concentration of the acid.

Constant volume of Sodium Hydroxide Solution (NaOH): 50.0 cm3 

Concentration of Sodium Hydroxide Solution (NaOH):  2M 

Concentration of Hydrochloric acid (HCl):  1M

ASPECT 2
Data Processing

  * Calculate the heat produced of the reaction:

Reaction: HCl (aq) + NaOH (aq) = NaCl (aq) + H2O (l)

H reaction= (Mass of NaOH)(Specific heat capacity)(∆T)...
