WebJan 20, 2010 · The pH scale goes from 0 to 14. A fluid with a pH of 7 is neutral. Below 7, it is acidic; above 7, it is alkaline. A small drop in pH means big change in acidity: The pH of seawater is near 8, which makes it mildly alkaline, or basic; but any decrease in the pH of a liquid is considered “acidification.”. The key danger factor is an increase ... WebpH is a representation of hydrogen ion activity in a liquid. It is the negative logarithm of the number of hydrogen ions (in moles) per liter of liquid. Thus: 10 -11 moles of hydrogen ions in 1 liter of liquid = 11 pH. 10 -5.3 moles of hydrogen ions in 1 liter of liquid = 5.3 pH.

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. WebpH = −log [H+] The square brackets around the H + automatically mean "concentration" to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold. Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic). dababy mother and father
