Final answer:
Additives can affect the hydrogen bonds between water molecules by disrupting their structure and altering water's properties.
Step-by-step explanation:
Hydrogen bonds form between water molecules due to the attraction between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. Additives can affect these hydrogen bonds by disrupting the structure of water molecules and altering their properties.
For example, when ionic compounds are added to water, the individual ions react with the water molecules and their ionic bonds are disrupted in the process of dissociation. The resulting spheres of hydration, or hydration shells, that form around the ions keep them separated in the water.
Overall, additives can impact the strength and stability of hydrogen bonds in water, leading to changes in the physical and chemical properties of water.
