Study Notes
Properties of Water
- Water consists of two elements: Oxygen and Hydrogen in a 1:2 ratio.
- Formed through covalent bonds, where atoms share electrons.
Polarity of Water
- Oxygen shares electrons with Hydrogen, but not equally due to electronegativity; Oxygen has a stronger attraction to the shared electrons.
- This unequal sharing leads to polarity, creating a polar covalent bond within the water molecule.
- Polarity allows water to form hydrogen bonds with itself and other charged molecules.
Hydrogen Bonds
- Hydrogen bonds are weak attractions between water molecules or other charged entities.
- When two water molecules bond together, this is termed cohesion.
Cohesion and Adhesion
- Cohesion occurs between water molecules due to opposite charges attracting and forming hydrogen bonds.
- Adhesion is the bond formed between different molecules, such as an amino acid and water, highlighting the interaction of polar molecules.
