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). 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.

WebDec 5, 2015 · Then we discover a report that Mg (OH) 2 can be considered to be a weak base (Ref 1), so we would expect a pH somewhat below 7.00, and the answer would be "0.1M MgCl 2 is acidic." (But not very acidic.) An elegant way of describing the situation is that Mg (OH) 2 is a strong electrolyte but a weak base (Ref 2 and 3).
