1. Solvent
2. Low Density
3. Cohesive
4. High Heat Capacity
5. Lubricant
6. Neutral pH
The water molecule is formed by highly negative oxygen ions being attracted to the highly positive hydrogen ions, creating a strong and polar bond.

More H+ less pH
The presence of Hydrogen ions in a solution. That being, substances with a pH less than 7 are acidic and greater than 7 are basic.
Mouth: 7 Stomach: 2.5 Small Intestine: 8.5
Blood: 7.38-7.40
Buffers
Help to resist changes to pH to maintain a steady environment, called homoeostasis
