It includes exercises that challenge students … Read more
Worksheet Description Chromatography is a laboratory or separation technique used to separate and analyze the components of a mixture based on their differential affinities to a mobile phase and a stationary phase. Do you understand how paper chromatography works or the principle behind it? Can you analyze a chromatogram and explain it to a layman? … Read more
Worksheet Description Distillation is a separation technique that’s commonly used to separate components of mixtures by exploiting differences in their boiling points. Do you understand how the process works? Do you understand the difference between the most common types of distillations? This worksheet is designed to assess students’ understanding of distillation as a method of … Read more
Fractional distillation is a separation technique used to separate components of mixtures based on their boiling point differences. It is more efficient compared to simple distillation and that’s why it is often used to separate components with closer boiling points (less than 400C). In contrast, simple distillation is typically used when the boiling points of … Read more
Worksheet Description What is the difference between a solution, solute, and solvent in chemistry? Can you identify a solvent and a solute in a solution? This worksheet is designed to assess students’ understanding of solutes, solvents, and solutions. It comprises exercises that require students to define and recognize solvents and solutes in solutions, alongside testing … Read more
