Amanda Evans 1.5 identify examples of buffer solutions and their practical uses Changes in pH can harm cells and any living organisms. Buffers are solutions that resist changes in pH when acids or bases are added to them, consisting of weak acids and their conjugate bases. The concentrations of the weak acid and the salt are large in contrast to the amount of protons/hydrogen's that are added or removed. Water or simple aqueous solutions do not maintain their pH well because of the effects of impurities such as carbon dioxide. Solutions can be made with a constant pH even if small quantities of acid and alkali are added to it. 1) Natural buffers are chemicals that the body releases into the blood stream to help maintain a healthy pH level. Carbon dioxide (CO2) acts as an acid by donating hydrogen ions when needed and forms carbonic acid when it dissolves in water. Carbonic...
