Properties of Water
- Water is an important constituent of biochemistry, the study of biological reactions.
- Cells contain approximately 70-90% water.
- Water molecules cling to each other due to hydrogen bonding.
- Water plays a role as an important solvent and determines the pathway taken by the water.
- Those molecules that can attract water are said to be hydrophilic.
- Nonionized and nonpolar molecules that cannot attract water are said to be hydrophobic.
- Water molecules are cohesive and adhesive.
- Due to cohesion, water shows surface tension.
- Water has a high heat capacity.
- Water is not a linear molecule. It has a bent shape. This is because the highly electronegative oxygen pulls the electrons from the hydrogen closer and gains a partial negative charge. This makes hydrogen partially positive.
