Time-Release Vitamin C Tablets

Figure from experiment 31 from Chemistry with Vernier

Introduction

By slowly releasing a vitamin or a medicine throughout the day, timed-release tablets offer a simple alternative to multiple doses. There are several different methods used to achieve the timed-release effect. One common method involves covering the medicine with a polymer coating that allows it to slowly permeate into the body.

Objectives

In this experiment, you will

  • Compare the behavior of timed-release vitamin C tablets with regular vitamin C tablets when each is added to distilled water.
  • Use a pH Sensor to monitor the pH value of the two different types of vitamin C tablets over an elapsed time of approximately twelve minutes.
