A titration was performed using 10.0 mL of 1.5 M HCl and appropriate amount of NaOH solution. The purpose of this investigation is to experimentally determine the molar concentration of acetic acid in vinegar. Remember to read the buret to the nearest. The electrodes are rinsed and blotted again after the measurement and returned to the pH 7 buffer solution. For this experiment, the titration volumes will be easier to enter into the MicroLab software if the starting volume of NaOH is EXACTLY 0.00 mL. Many titrations are acid-base neutralization reactions, though other types of titrations can also be performed. calculate initial concentrations of monoprotic acids from titration … View the graph generated by the MicroLab titration program to become familiar with the appearance of a typical titration curve. Consider a 0.238 M aqueous solution of sodium hydroxide, NaOH. One type of titration uses a neutralization reaction, in which an acid and a base react to produce a salt and water: In equation 1, the acid is HCl (hydrochloric acid) and the base is NaOH (sodium hydroxide).

Make sure to fill the tip with NaOH solution by draining some solution from the tip into a waste beaker. To gain experience monitoring a titration with a pH electrode and determining the equivalence point. Solubility equilibria. Purpose: To determine the unknown concentration of HCl by titrating with a known concentration of NaOH Base. This ensures that all of the NaOH delivered from the buret ends up in the reaction mixture. 3.06 Titration Lab Report for 3.07 Discussion Please go to 3.06 Investigation and watch the tutorial for the Titration Lab. Compare and sketch a titration graph for a strong acid/strong base titration and the same titration after a buffer solution has been added. Stop at ~8.0 mL of titrant volume. Acid-base titrations. Before leaving, go to a computer in the laboratory and enter your results in the In-Lab assignment. After a buffer has been added the graph has leveled off at the equivalence point. identify if an unknown acid is weak or strong and monoprotic or polyprotic. Be sure to bring a disk to lab to store data files. It can attack the skin and cause permanent damage to the eyes. A titration is … During a titration, the volume of one reagent, the analyte, is predetermined while the other reagent, the titrant, is prepared in a buret and slowly introduced to the analyte solution. 02 Thursday, December 19, 2013 Introduction The following lab was an acid-base neutralizing titration. A student did not read the directions to the experiment properly and mixed up where to place the NaOH solution and the vinegar.
