The math that tells you whether something's acidic, alkaline, or just vibing neutral.
means Using the formula pH = -log[H+] to measure hydrogen ion concentration and determine a substance's acidity or basicity on a scale from 0 to 14.
from Coined by Danish chemist Søren Peder Lauritz Sørensen in 1909 at the Carlsberg Laboratory, where he needed to control beer quality. The 'p' stands for the German word potenz (power), making it literally the power of hydrogen—elegant and nerdy.
pool maintenance — Keeping pH 7.2-7.6 prevents corrosion and chlorine inefficiency
fermentation science — Brewers calculate pH drops as yeast produces lactic acid during brewing
soil testing — Farmers adjust fertilizer based on soil pH calculations for crop yield
pharmaceutical development — Drug solubility and absorption depend entirely on pH calculations
