properties of water and pH

structure

H20

polarity

the oxygen atom has a slightly negative charge and the hydrogen atoms have a slightly positive charge, making it a polar molecule. Polarity leads to hydrogen bonding because the negatively charged oxygen bonds with the positively charged hydrogen.  

cohesion

water molecules stick to themselves

adhesion

water molecules stick to other surfaces 

capillary action

the ability of water to flow in narrow spaces against gravity, due to cohesion and adhesion.

surface tension

the force that causes the surface of a liquid to resist external forces, because of cohesion.

high specific heat

It takes a lot of energy to raise the temperature of water, which helps regulate climate and maintain temperature stability in aquatic environments because of its stable temperature.

high heat of vaporization

the amount of energy required to convert water from liquid to gas, allowing for cooling effects in nature.

density properties

water is denser as a liquid than as a solid, allowing ice to float.

universal solvent

Water can dissolve many substances (not all)

pH scale 

0-6 is acidic (high H+ concentration, low OH- concentration)

7 is neutral (equal concentration of H+ and OH-)

8-14 is basic (high OH- concentration, low H+ concentration)

pH importance

It keeps the enzymes working properly which regulates your crucial bodily functions like and makes sure everything is working correctly and smoothly.
