How to Convert Between pH & Hydronium Ion Concentration

WebIn chemistry, pH (denoting the “power of hydrogen” or “potential of hydrogen”) is a scale used to measure the acidity or alkalinity of a given aqueous solution. Pure water (H 2 O) is a non-electrolyte, but at room temperature it contains a very small and equal amount (1.0 × 10 -7 M) of both hydronium (H +) and hydroxyl or hydroxide (OH ... WebIn this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H +] , we can solve for [H +] as, − pH = log [H +] , [H +] = 10 −pH, by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,
