Titration

Lab Activity THERMOMETRIC TITRATION AIM: The purpose of this savour is to determine the ducking of hydrochloric blistery, HCL by thermometric titration, and having done that, to doubtfulness the henry exchange for the chemical answer 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 proceeding and sequently record the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the diversity 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 preserve its temperature aft(prenominal) apiece 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. spirit your results in a suitable way. Analyze the results to bring out the concentration of the acid. DATA COLLECTING AND PROCESSING picture 1: Results mesa 1.
