SCH4U –Acid-Base Titration Lab: Determining the Ka of Acetic Acid (Online Version)Pre-Lab Questions: Research and respond to these questions1.With respect to a titration, explain the termsequivalence pointandendpoint./12.A titration uses specific equipment. Refer to the diagram below and research how a simple titration isset-up and explain what the following equipment is used for: Burette, Erlenmeyer Flask, Acid-BaseIndicator, Retort Stand./23.When using phenolphthalein indicator in a titration, why is it necessary to have the sodium hydroxidesolution in the burette, rather than in the Erlenmeyer flask?/14.During titrations, a white piece of paper is usually placed under the Erlenmeyer Flask. What is the pointof doing this?/15.Research the Ka for acetic acid. Is this a strong or weak acid.What does this mean?/26.Write the equation of the ionization of weak formic acid (HCOOH(aq)) and write the Kaexpression. /17.10 mL of a 0.20 M HCl(aq) is the analyte in a titration. Calculate the concentration of the NaOH solutionif 15 mL are required to reach the endpoint./2
