What is "pH" - Definition & Explanation

pH is the measure of acidity or alkalinity of a substance. On a scale of 0-14, 7 is neutral (neither acid nor alkaline). Lower than 7 is acidic (gives up a hydrogen atom when added to water) and greater than 7 is alkaline (a base), giving up OH (hydroxide) when added to water. The further away the number is from 7, the "stronger" it is. Each fabric has a preferred pH. PH is also used in water-based cleaning as some soils yield to different pH solutions.
