Titration of a Weak Base Prelaboratory Questions 1. Will addition of HCl to a solution make it more acidic or more basic? Will the pH increase or decrease? How does an end point differ from an equivalence point? 2. were titrated with a standard HCl solution: 3. Aliquots of an unknown tris sample Use the balanced equation to set up the string calculation showing how the tris a. mol of acid, L of acid. mo of base, and L of concentration will be calculated. Use L base to represent the reactants. Remember the calculation must include a stoichiometric ratio. b. A 20.00 mL aliquot of tris was titrated with 0.1009 M HCI. The sample required 20.67 mL HCI to reach a BCG endpoint. What is the molarity of the tris solution? 63
4. Why is titrant added rapidly at the beginning of a titration but more proceeds? slowly as the titration 5. A tris sample was titrated with 0.09857 M HCl solution. The initial buret reading was 1.84 mL and the final buret reading was 37.86 mL. A student recorded the initial volume as 1.8 mL and the final volume as 37.9 mL. State twoways this error will change the reported molarity of the tris.

    Standardization of NaOH: Acid Base Titration Objective: In this lab, you will accurately determine the concentration of a solution of sodium hydroxide (NaOH) using a 0.500M potassium hydrogen phthalate (KHP) standard solution. Background: Acid–Base Titrations When an acid reacts with a base, a neutralization reaction occurs. The H+ ions from the acid and the HO– ions from the base combine to form water and are therefore neutralized. The other product of reaction is a salt. For example, hydrochloric acid reacts...
