M atch these terms with the correct statement or definition: Acids Bases Buffers Salts 1 . Substances that are proton (H+) donors. 2 . Substances that accept protons. 3 . Molecules consisting of a positive ion other than hydrogen and a negative ion other than hydroxide. 4 . Chemicals that resists changes in pH when acids or bases are added to a solution. B. M atch these terms with the correct statement or definition: Acidic solution Alkaline (basic) solution Neutral solution 1 . pH of 7 (e.g., pure water). 2 . pH less than 7. 3 . Greater concentration of hydroxide ions than hydrogen ions. A change in the pH of a solution by one pH unit represents a 10-fold change in the hydrogen ion concentration.
