Çözeltiler: Classifications and Properties
Çözelti çeşitleri (Types of solutions) can be classified based on various factors:
- Amount of dissolved substance:
- Doymuş çözelti (Saturated solution)
- Doymamış çözelti (Unsaturated solution)
- Aşırı doymuş çözelti (Supersaturated solution)
Definition: Çözünürlük (Solubility) is the maximum amount of solute that can be dissolved in a given amount of solvent.
- Concentration of solute:
- Derişik çözelti (Concentrated solution)
- Seyreltik çözelti (Dilute solution)
Example: For salt solutions, 25g salt in 100g water is saturated, while 30g salt in 100g water is supersaturated.
- Electrical conductivity:
- Elektrolit çözeltiler (Electrolyte solutions)
- Elektrolit olmayan çözeltiler (Non-electrolyte solutions)
Vocabulary: Elektrolit çözeltiler conduct electricity due to the presence of ions, while non-electrolyte solutions do not.
Çözelti türleri (Solution types) can also be categorized based on the physical states of the solvent and solute:
- Katı çözelti örnekleri (Solid solution examples): Metal alloys
- Sıvı çözelti örnekleri (Liquid solution examples): Sugar water, alcohol-water mixtures
- Gaz çözelti örnekleri (Gas solution examples): Air
Highlight: Understanding the properties and classifications of mixtures and solutions is crucial for 10.sınıf kimya karışımlar (10th-grade chemistry mixtures) curriculum.
