pH scale ranges from 0-14
pH of 7 is NEUTRAL
pH <LESS THAN 7 is Acidic
ph >GREATER THAN 7 is Basic/Alkaline

Cabbage Juice Indicator for pH
Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution.

Surface Tension--strong bond between water molecules at the surface
Cohesion--(co=together) Water molecules bonding to other water molecules
Adhesion--water molecules bonding to different molecules
Polarity--opposites attract, positive and negative charges, ability to dissolve water
Capillarity Action--force that pushes water in the opposite direction (against gravity)--this is how plants get their water
