This video addresses specification points 1.3-1.7C in the IGCSE Chemistry 2017 specification. This includes definitions of solute, solution and saturated solutions, a discussion of dilution and diffusion experiments, the units of solubility and the interpretation of solubility curves. Each point is covered, followed by a short discussion of how this content is commonly examined.
1.3. Understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained
1.4 Know what is meant by the terms:
Solvent
Solute
Solution
Saturated solution
1.5C. Know what it meant by the term solubility in the units g / 100 g of solvent
1.6C. Understand how to plot and interpret solubility curves
1.7C. Practical: Investigate the solubility of a solid in water at a specific temperature
