This editable 37-slide PowerPoint covers concentration calculations and the preparation of standard solutions for Pearson BTEC Applied Science Unit 1 Chemistry. Designed to develop students’ understanding of solution chemistry and practical laboratory techniques, the lesson provides clear explanations, worked examples, calculation activities and practical applications.

The resource introduces solutions, solutes and solvents before exploring concentration as the amount of solute present in a given volume of solution. Students learn about molarity and how to calculate concentration, amount and volume using the equation n = cV. Clear worked examples demonstrate how to rearrange equations, convert between cm³ and dm³, and calculate concentrations in both mol dm⁻³ and g dm⁻³.

The lesson then introduces standard solutions, defined as solutions with accurately known concentrations. Students learn how to calculate the mass of solute required to prepare a standard solution, using sodium carbonate as a worked example. The resource also explores the importance of accurate measurements, volumetric glassware and correct laboratory techniques when preparing solutions.

The PowerPoint includes a starter activity with answers, clearly defined learning objectives, key scientific vocabulary, step-by-step calculations, guided practice activities and a practical activity focused on preparing a standard solution. Ten check-your-understanding questions with answers provide opportunities for assessment and consolidation.

Ideal for classroom teaching, practical preparation, independent learning and revision, this resource supports students studying Pearson BTEC Level 3 Applied Science Unit 1 Chemistry.
