Ph of earth
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. WebFeb 9, 2024 · Seawater has a pH of 8.2 on average because it contains naturally occurring alkaline ions that come primarily from weathering of continental rocks. When seawater absorbs carbon dioxide from the atmosphere, carbonic acid is produced (see Box 1), reducing the water’s pH.
