WebFeb 10, 2014 · When water is in a pure or distilled state, it measures a pH of 7. The lower the number (0-7), the more acidic it’s considered. And the higher the number (7 to 14), the more basic it is. The pH scale may seem small, but each whole number represents a ten-fold leap in concentration of either H ions or OH ions. WebEach one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14. It's a lot easier to use a logarithmic scale instead of always having to write down all those zeros!
