WebHow do hydrogen ions relate to the pH scale? A lower concentration of hydrogen ions equals a high pH number; a higher concentration of hydrogen ions equals a low pH number. Sketch a monosaccharide, amino acid, nucleotide, glycerol molecule, and fatty acid. Then show how these similar molecules form carbohydrates, proteins, nucleic acids, or fats. WebMay 6, 2024 · The International Union of Pure and Applied Chemistry (IUPAC) has a slightly different pH scale that is based on electrochemical measurements of a standard buffer solution. Essentially, the definition uses the equation: pH = -log a H+. where a H+ stands for hydrogen activity, which is the effective concentration of hydrogen ions in a solution.
