Which term describes a substance that produces a solution with more hydrogen ions than hydroxide ions?

• A. Base
• B. pH
• C. Salt
• D. Acid

Answer: (D)

Acidity comes from having more hydrogen ions than hydroxide ions in solution. When acids dissolve in water, they release H+ (which in water becomes H3O+), increasing the hydrogen ion concentration. A solution with higher H+ is acidic and has a pH below 7. Bases do the opposite by increasing OH−, lowering the relative H+ and giving a higher pH. A salt doesn’t inherently indicate acidity or basicity. So the term that describes a substance producing more hydrogen ions than hydroxide ions is acid.
