Understanding Solubility and Molecular Polarity
This page provides a comprehensive overview of çözünme nedir whatissolubility and the concepts of polar and apolar molecules. It explains the fundamental principle behind solubility and provides examples of polar and apolar substances.
The document begins by stating the basic principle of solubility: "like dissolves like". This concept is crucial for understanding how different substances interact in solution.
Definition: Çözünme Nedir - Solubility is the process by which a substance solute dissolves in a solvent to form a homogeneous mixture.
The page then distinguishes between polar and apolar substances:
-
Polar madde Polarsubstances:
Dissolve in polar solvents
Have an uneven distribution of charge
Contain unpaired ions
Examples include ionic compounds
-
Apolar madde Apolarsubstances:
Dissolve in apolar solvents
Have an even distribution of charge
Do not contain unpaired ions
Examples include noble gases
Highlight: The polarity of a molecule significantly affects its solubility properties. Polar ve apolar maddeler behave differently in various solvents.
The document provides visual representations of molecular structures to illustrate the difference between polar and apolar molecules. Some examples include:
Example:
- H-H and H-B-H are apolar molecules
- H-F and H-O-H water are polar molecules due to the presence of unpaired ions
The page concludes with extensive lists of common polar and apolar substances:
Vocabulary:
- Polar maddeler examples: H₂O, NH₃, HF, HCl, HBr, HI
- Apolar maddeler examples: CH₄, C₂H₆, Br₂, N₂, CCl₄
