Help learners scaffold titration calculations using ramped worksheets exploring the table method
This resource accompanies the Education in Chemistry ideas article Explaining titration.
Titration calculations can be challenging for learners as they can find it difficult to work out where to begin. You will explore the table method to help learners scaffold the calculations and use this to calculate the concentration of one of the solutions.
Learning objectives
- Explore the table method for structuring titration calculations
- Identify values for concentrations and volumes of solution and correctly identify which reactant these values apply to
- Use n=cV/1000 to carry out calculations involving moles (n), concentration (in mol/dm3) and volume (in cm3)
How to use this resource
You can use these scaffolded worksheets during a lesson when teaching titration calculations, or in a revision or intervention lesson. The resource can be used with or without the printed question sheets as the questions and answers are also found in the lesson slides.
Scaffolding
This resource focuses on using the table method for scaffolding calculations involving reacting solutions. This method is useful for learners who find calculations in quantitative chemistry difficult to carry out. When learners have become more confident, you can remove the scaffolding. You should aim to do this for learners who are likely to study chemistry beyond 14–16.
There are three versions of this resource:
- Sheet 1 (one star in the header) is fully scaffolded with the key information in each question already transferred to the tables.
- Sheet 2 (two stars in the header) has faded scaffolding and leads to learners applying the method independently by question 5.
- Sheet 3 (three stars in the header) has just the tables and is useful for enabling learners to develop fluency with the table method.
Answers
Answers to the questions on all student sheets can be found in the teacher notes.
