Final answer:
The statement indicating that constituents ionized from hydrogen make body fluids more acidic is true, as the release of hydrogen ions increases the acidity of solutions. The pH scale measures acidity or alkalinity, and water acts as a buffer in the human body, helping to regulate pH levels.
Step-by-step explanation:
When hydrogen ions (protons) are released in water, they can lead to an increase in the acidity of the body fluids. The statement that a constituent of water and most organic molecules ionized from Hydrogen makes body fluids more acidic is true. pH scale varies between 0 to 14, with values below 7 being acidic and values above 7 being alkaline. In pure water, a tiny fraction of water molecules can split to form hydronium ions (H3O+) and hydroxide ions (OH-), which contributes to the solution's acidity or alkalinity. Moreover, water acts as a buffer in human blood, helping to maintain pH within a narrow, healthy range, despite the introduction of acidic or alkaline substances.
When acid is present in water, it donates hydrogen ions, increasing the concentration of hydronium ions in comparison to pure water, thereby making the solution more acidic. The presence of these ions is what determines the pH of water and thus its acidic or basic nature. Additionally, the hydrogen bonds and van der Waals interactions provide necessary interaction between water molecules and other compounds dissolved in water, influencing pH and the structure of acids and bases.
