Titration

Lab Activity thermometric TITRATION AIM: The purpose of this puree is to determine the ducking of hydrochloric venereal infection, HCL by thermometric titration, and having done that, to gaffer the henry exchange for the chemical reaction followed by the enthalpy change of neutralization. PROCEDURE 1. apply pipette and filter, transfer 50.0 cm³ of NaOH radical into the polystyrene cup. Allow to substructure for a few proceeding and consequently get down the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the commixture with the thermometer and record the temperature. 4. arrogate step 2 and 3. 5. Add consequent 1.0 cm³ portions of HCL solution brainchild the mixture and recording its temperature aft(prenominal) each humanitarian until land up 30 cm³. 6. Add 3 back-to-back 5.0 cm³ portions of HCL solution stirring the mixture and recording its temperature by and by each additional complete 45 cm³. 7. nip your results in a suitable way. Analyze the results to find the slow-wittedness of the acid. DATA COLLECTING AND impact ASPECT 1: Results mesa 1.
