Solubility and Solution Types

The video tutorial by Miss Rediken covers the concept of solubility, focusing on how different factors affect the solubility of solids and gases. It explains that heating, stirring, and crushing can increase the solubility of solids, while cooling and increasing pressure are necessary for gases. The tutorial also teaches how to read solubility tables and understand saturation levels qualitatively, using terms like supersaturated, saturated, and unsaturated. Practical examples are provided to reinforce the concepts, and students are encouraged to practice interpreting solubility scenarios.

Which method will NOT increase the rate at which a solid dissolves in water?

• Cooling the water

• Crushing the solid
