-Polar or non-polar

-water polarity allows it to dissolve other polar substances easily

-when a polar substance is put in water, the positive ends are attracted to the negative ends of the molecule and vise versa

4
New cards

Universal Solvent.

Water is the universal solvent because it dissolves most substances.

5
New cards

Solubility

The degree in which a substance dissolves in a solvent to make a solution

6
New cards

Capillary action

The movement of water within the spaces of a porous material due to the forces of cohesion, adhesion, and surface tension

(Remember flowers in class)

7
New cards

Surface tension

-The property of a surface that allows it to resist an external force due to the cohesive nature of water molecules

-a force which causes a layer to behave like an elastic sheet or skin

-molecules at the surface form a stronger bond

8
New cards

Meniscus

A curve in the surface of a molecular substance (water) when it touches another material.
