Which term describes any substance that increases the concentration of hydrogen ions in a solution?

Explanation:
Acid describes any substance that increases the concentration of hydrogen ions in a solution. In water, acids dissociate to release H+ (often seen as H3O+), which lowers the pH of the solution. This aligns with the Arrhenius view used in many environmental and chemical contexts. Bases do the opposite by increasing hydroxide ions or accepting protons, which raises pH. Hazard and dose pertain to risk and amount, not the behavior of a substance in solution.
