Titration

Lab Activity THERMOMETRIC TITRATION AIM: The purpose of this test is to determine the ducking of hydrochloric sulphurous, HCL by thermometric titration, and having done that, to gallery the heat content exchange for the chemical reaction 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 legal proceeding and incidentally record the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the medley 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) to each one 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 4 5 cm³. 7. spirit your results in a suitable way. Analyze the results to hazard the concentration of the acid. DATA COLLECTING AND PROCESSING boldness 1: Results mesa 1. Raw Data ( good deal of Hydrochloric acid vs. temperature of the reaction between the substances) Volume of HCl (±0.5 cm³)| Temperature of HCl + NaOH (±0.1°C)| 5| 21.2| 10| 21.4| 11| 23.1| 12| 23.1| 13| 22.9| 14| 22.9| 15| 22.8| 16| 22.
