the definition of pH Watch
The definition of pH: The potential of Hydrogen; the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per litre; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution, where 7 is neutral and greater than 7 is acidic and less than 7 is basic
i just need a dumbd down version of it, and i cant seem to put it into words
so it is basically a measure of H+ concentration. As H+ increases, pH decreases but it isn't actually on a measure of 0 to 14 as the google definition says: it's just most solutions you meet fall into this range. There is nothing stopping a solution having a negative negative pH if the H+ concentration is more than 1M.
