Study Notes
Methods of Separating Mixtures
- Filtration uses a screen to allow liquid particles to pass through while trapping solid particles.
- Magnetism is utilized in magnetic separation to attract and remove ferrous materials from mixtures.
- Decantation involves pouring off a liquid to separate it from another liquid or solid that remains behind.
- Sieving utilizes physical properties such as particle size, shape, and color to distinguish between different components.
- Distillation separates mixtures based on differences in boiling points, allowing for the isolation of liquids.
Characteristics of Acids and Bases
- Acids are characterized by their sour taste, ability to conduct electricity, and turning blue litmus paper red.
- Bases generally have a bitter taste, are slippery to the touch, and turn red litmus paper blue.
- The pH range for bases typically spans from 8 to 14, indicating their alkalinity.
Common Acids
- Sulfuric acid (Hâ‚‚SOâ‚„) is a commonly used acid found in car batteries.
- Hydrochloric acid is the common name for HCl, a strong acid used in various applications.
