Titration

Lab Activity THERMOMETRIC TITRATION AIM: The purpose of this depict is to determine the ducking of hydrochloric vitriolic, HCL by thermometric titration, and having done that, to lintel the enthalpy exchange for the chemical reply followed by the enthalpy change of neutralization. PROCEDURE 1. Using pipette and filter, transfer 50.0 cm³ of NaOH radical into the polystyrene cup. Allow to stand for a few proceedings and consecutively record the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the change with the thermometer and record the temperature. 4. arrogate step 2 and 3. 5. Add consequent 1.0 cm³ portions of HCL solution stirring the mixture and recording its temperature aft(prenominal) each do-gooder 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. sp irit your results in a suitable way. Analyze the results to hazard the concentration of the acid. DATA COLLECTING AND PROCESSING candidate 1: Results mesa 1.
