Investigation 14

How do the structure of the acid and the initial concentration of an acid and a base

influence pH of the resulting solution during titration?

Before the Lab

• Answer the prelab questions prior to lab. • Complete the simulation titration• Print the Help sheet for Titration

Lab Procedure

• Follow the lab procedure for titration of vinegar. (separate and new handout)

• Complete the calculations at the end of the lab (molarity of acetic acid in vinegar and mass percent of acetic acid in vinegar)

For Friday:

• Answer In-Lab discussino questions • Refer to the graph for few questions (you will

not have to construct a titration graph from your data)

Use the following graphs to answer any questions
