Titration

Lab Activity THERMOMETRIC TITRATION AIM: The purpose of this sweat is to determine the ducking of hydrochloric battery-acid, HCL by thermometric titration, and having done that, to organize the heat content exchange for the chemical 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 proceedings and endly record the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the assortment 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 arranging 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 complet e 45 cm³. 7. spirit your results in a suitable way. Analyze the results to decree the concentration of the acid. DATA COLLECTING AND PROCESSING scene 1: Results mesa 1.
