Mixtures
Learning Time: 3-10 hours
Content: Mixtures are the study of systems formed by combining different substances without losing their chemical properties. This area covers homogeneous and heterogeneous mixtures, solutions, colloids, suspensions, concentration types (percentage, ppm), and mixture properties. TYT focuses on basic mixture types, while AYT focuses on colloid chemistry and industrial applications. The current 2025 curriculum also covers environmentally friendly mixture designs and materials science. Learning this topic provides a fundamental understanding of the separation and use of substances.
