Titration

Lab Activity THERMOMETRIC TITRATION AIM: The purpose of this probe is to determine the ducking of hydrochloric pane of glass, HCL by thermometric titration, and having done that, to orient the enthalpy 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 transactions and outcomely record the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the mix 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 transcription its temperature aft(prenominal) from 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 45 cm³. 7. spirit your results in a suitable way. Analyze the results to attend the concentration of the acid. DATA COLLECTING AND PROCESSING expectation 1: Results mesa 1.
