Describe the properties of water that are critical to maintaining life; Explain why water is an excellent solvent; Provide examples of water’s cohesive and adhesive properties; Discuss the role of acids, bases, and buffers in homeostasis
1. Water is highly cohesive and adhesive: Because of hydrogen bonds, water molecules develop strong intermolecular attraction between them. This is called cohesion. When water form hydrogen bonds with other substance, the attraction is called adhesion.
Water has many properties that are critical to maintaining life. It is a polar molecule, allowing for the formation of hydrogen bonds, which allow ions and other polar molecules to dissolve in water. Therefore, water is an excellent solvent.
Although water consists of simple molecules, each containing just three atoms, its structure gives it unique properties that help explain why it is vital to all living organisms. Figure \(\PageIndex{1}\): Planet Earth
Water has many essential roles in living organisms due to its properties: The polarity of water molecules; The presence and number of hydrogen bonds between water molecules; Solvent. As water is a polar molecule many ions (e.g. sodium chloride) and covalently bonded polar substances (e.g. glucose) will dissolve in it

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density. Review. Describe the structure of a water molecule. What is polarity, and why is water polar? Explain how hydrogen bonds cause molecules of liquid water to stick ...
Describe the properties of water that are critical to maintaining life. Distinguish between hydrophilic and hydrophobic molecules. Explain why water is a good solvent for many solutes. Explain the pH scale using the specified terms; indicate how much more (or less) acidic one substance is compared to another using the pH scale
