What we have learnt
- Solutions are homogeneous mixtures formed by the dissolution of solutes in solvents.
- The solubility of a substance can vary depending on temperature and the nature of the solvent and solute.
- Acids produce hydrogen ions in solution, whereas bases produce hydroxide ions, with their properties measurable on the pH scale.
Key Concepts
- -- Solution
- A homogeneous mixture formed when a solute dissolves completely into a solvent.
- -- Solubility
- The maximum amount of solute that can dissolve in a given amount of solvent at a specified temperature and pressure.
- -- pH Scale
- A measure of the acidity or basicity of a solution, ranging from 0 to 14, where lower values are acidic and higher values are basic.
- -- Neutralization
- A chemical reaction between an acid and a base that produces a salt and water.
- -- Universal Solvent
- A term often used to describe water due to its ability to dissolve more substances than any other liquid.
