Water Properties and Interactions: Hydrogen Bonding, Polarity, Cohesion, Adhesion, Solvent Role, Surface Tension, Thermal Capacity

Hydrogen bonding:

an electrostatic interaction that occurs when a hydrogen (H) atom is bound to an electronegative atom.

Water polarity:

water has uneven charges, oxygen is much stronger and has a pull on electrons.Oxygen is more electronegative.

Cohesion:

water molecules that bond to other water molecules

Adhesion:

water molecules bond to to different molecules other than itself.

Solvent:

to dissolve in liquid, water is an example.

Why is water a good solvent?

Because it has an uneven distribution of charge. (polar), it forms hydration spheres around molecules and ions to break apart the solids together.

Surface tension:

Liquids that act as if the surface has a skin. This is because of cohesion.

Thermal capacity of water:

Energy required to raise its temperature. Water has high thermal capacity as it requires alot of energy.
