Module 7 Overview

WHAT YOU’LL LEARN TO DO: Use titrations to calculate the concentration of citric acid in a soda; calculate the concentration of NaOH by titrating with a primary standard then use NaOH as a secondary standard to determine the acid content of Sprite

Please note:

  • There are 2 separate assignments for this lab.
    • Assignment 1: The lab handout that may be completed as a group (the same as for all labs to date).
    • Assignment 2: This is an individual assignment that is designed to show your knowledge of the lab and course content. You will type a formal lab report. Please see the directions and rubric for more help.

Learning Objectives

By the end of this section, you will be able to:

  • Calculate the concentration of a secondary standard through titration with a primary standard.
  • Titrate a sample of carbonated soda with a standard solution to determine the concentration of acid in the beverage.
  • Distinguish between endpoint and equivalence point with the addition of indicator to your sample.
