In this lesson you will learn how to approach titration problems and about acid-base indicators.
By the end of this lesson, students should be able to:
- strategize the solution to titration problems that involve stoichiometric and equilibrium steps.
- describe the methods used to determine equivalence points in titrations.
- explain what acid-base indicators are and how they work.
- determine the pH at which an indicator changes colour.
- describe the criteria for choosing an appropriate indicator for strong acid-strong base titrations and titrations of weak acids.
- Use a chart of useful pH ranges for common indicators together with any given equivalence point to find the most suitable indicator.
Let’s begin by watching the tutorial below on how to approach and solve titration problems.
Below is the video lesson on Acid-Base indicators. Please watch it and take down notes.
In order to gain practice solving titration and acid-base indicator questions, please answer the questions in the worksheet below. All answers are provided at the bottom.
