What “p2h2” means
Wiktionary · Wikipediaph
- adverbIn the way it sounds, particularly: written to describe the sound rather than the dictionary spelling.
- nounA photometric unit of illuminance, or luminous flux through an area (symbol ph).
In chemistry, pH is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. While the origin of the symbol 'pH' can be traced back to its original inventor, and the 'H' refers clearly to hydrogen, the exact original meaning of the letter 'p' in pH is still disputed; it has since acquired a more general technical meaning that is used in numerous other contexts.
