A student makes a solution that simulates stomach acid. Which of the following would be true of this solution, compared to distilled water?

Rationale

It has more hydrogen ions.

A solution that simulates stomach acid would contain a higher concentration of hydrogen ions (H⁺) than distilled water, which is neutral. This increased concentration of hydrogen ions results in a lower pH value, characteristic of acidic solutions.

A (It has a higher pH.) YOUR ANSWER

A solution that simulates stomach acid would have a lower pH compared to distilled water, which has a pH of 7. Stomach acid typically has a pH ranging from 1.5 to 3.5, indicating a higher acidity due to more hydrogen ions, thus contradicting the statement that it has a higher pH.

B (It has more hydrogen ions.) CORRECT

This statement accurately reflects the nature of stomach acid, which contains a significantly greater concentration of hydrogen ions compared to distilled water. The presence of these ions is what gives stomach acid its acidic properties and low pH.

C (It contains more hydroxyl ions.) YOUR ANSWER

Hydroxyl ions (OH⁻) would be present in lower concentrations in a solution simulating stomach acid than in distilled water. Since acids increase the concentration of hydrogen ions, the corresponding concentration of hydroxyl ions would decrease, making this statement incorrect.

D (It has more hydroxyl ions.) YOUR ANSWER

Similar to option C, this statement is false because a solution that simulates stomach acid has fewer hydroxyl ions compared to distilled water. The increase in hydrogen ions from the acid leads to a decrease in hydroxyl ions, thereby contradicting this option.

Conclusion

The accurate description of a solution simulating stomach acid is that it contains more hydrogen ions than distilled water, resulting in its acidic nature and lower pH. In contrast, the other choices incorrectly represent the relationship between hydrogen and hydroxyl ions in acidic solutions. Understanding these properties is essential for grasping the behavior of acids in biological contexts, particularly in digestion.
