A redox titration using wine
 

Description

Consider these questions and watch the video for ideas on how to use a redox titration to develop your students’ understanding of half-equations. Follow each page in sequence to assess your students’ theoretical and practical knowledge of a redox titration.

Sign up for our Redox online CPD course for similar content including over 116 different pages of teaching activities and videos.

The course includes nine Redox chemistry topics from Oxidation and Reduction to Electrolysis and Electrode potentials and it will take approximately nine hours to complete.

Redox titrations are an important context for work on half equations. In order to find the number ratio between reagents in a redox titration the student needs to produce half equations and combine them into a full equation. It is also good for students to experience titrations that are not based on an acid–base reaction. It is likely that students will be familiar with the techniques of titrations.

Consider your answers to the questions below before moving to the next page.

Q1. How can you ensure they really think through the experiment they are about to do, rather than jump straight in?

 

 

Q2. How can you best help students to improve their titration technique?

 

 

Q3. What are the common mistakes students make when doing titrations?

 

 

Q4. In an iodine titration how do you identify the end point?

ADDITIONAL INFORMATION

Redox reactions take us down an important conceptual pathway in chemistry. In our Redox chemistry course, we develop your understanding of redox, beginning with the gain and loss of oxygen and hydrogen to pave the way to understanding all chemical reactions as a rearrangement of electrons.

After working through the full course you will be able to:

  • understand the core ideas about redox;
  • explain how the conventions we use like oxidation number and electrode potentials work;
  • anticipate common misconceptions that arise and adapt your teaching to minimise these;
  • confidently deliver key experiments, demonstrations and activities that develop student understanding; and
  • access a wider range of activities and resources to support students' learning about redox reactions.
