Buffers

Buffers. Buffered Solutions. A buffered solution is one that resists a change in its pH when either hydroxide ions or protons (H 3 O + ) are added. Very little change in pH is witnessed even when a strong acid or base is added. The components of a buffer are a conjugate acid-base pair.

Acids, Bases, and pH

Acids, Bases, and pH. Acid Compound that increases the amount of hydrogen ions (H + ) that are present Usually starts with hydrogen (H) in their chemical formula Examples: Hydrochloric acid (HCl) Citric acid (H 3 C 6 H 5 O 7 ) Lactic acid (HC 3 H 5 O 3 ). Strong Acids
