What makes water “neutral “ (pH of 7)
Mandarinka [93]

Answer:

Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That's why 7 is neutral. ... In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.

Describe how cohesion and adhesion contribute to the upward movement of water through a plant.
Lilit [14]

Answer:

Both Cohesion and adhesion play an important role in the upward movement of water through a plant.

Explanation:

Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .

                  During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.

                    Adhesion deals with the interaction of water column with the wall of the xylem tissue.
