WebOne of the great wonders of the cell membrane is its ability to regulate the concentration of substances inside the cell. These substances include ions such as Ca ++, Na +, K +, and Cl –; nutrients including sugars, fatty acids, and amino acids; and waste products, particularly carbon dioxide (CO 2), which must leave the cell. WebAmmonium hydroxide (pK = 9.25) is an effective buffer against acid at pH 8.25. False, because acid will drive the solution out of the buffering range (as the buffering range of a buffer is its pK ± 1). The pK values for phosphoric acid are 2.15, 6.82, and 12.38. At pH 2.15, [H3PO4] = [PO43-]. greater celandine poppyWebThe hydroxyl ions (also known as hydroxide ions) or other basic substances combine with H + present to form a water molecule, thereby removing H + and reducing the solution’s acidity.
