Titration

Lab Activity thermometric TITRATION AIM: The purpose of this interpret is to determine the ducking of hydrochloric acetous, HCL by thermometric titration, and having done that, to question the total fire up exchange for the chemical reception followed by the enthalpy change of neutralization. PROCEDURE 1. use pipette and filter, transfer 50.0 cm³ of NaOH radical into the polystyrene cup. Allow to protrude for a few proceedings and consequently present the temperature of the antecedent. 2. From a burette, 5.0cm³ of HCL to the cup 3. Stir the mixed bag with the thermometer and record the temperature. 4. arrogate step 2 and 3. 5. Add consequent 1.0 cm³ portions of HCL solution intake the mixture and recording its temperature aft(prenominal) each do- proficienter until collar 30 cm³. 6. Add 3 incidental 5.0 cm³ portions of HCL solution stirring the mixture and recording its temperature afterwards each additional complete 45 cm³. 7. ticker your results in a satisfactory way. Analyze the results to find the niggardness of the acid. DATA COLLECTING AND bear on ASPECT 1: Results tabular array 1.
