WEBMar 4, 2024 · pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion—which ordinarily ranges between about 1 and 10 −14 gram-equivalents per litre—into numbers between 0 and 14.

WEBAbout. Transcript. The pH scale is used to determine the acidity or basicity (alkalinity) of a substance. Acidic substances have pH values below 7, while basic substances have pH values above 7; neutral substances have a pH of 7. The pH scale is logarithmic, so each step represents a 10-fold change in concentration. Created by Sal Khan. Questions.

pH - Simple English Wikipedia, the free encyclopedia
https://simple.m.wikipedia.org/wiki/PH
WEBpH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances that aren't acidic or alkaline (that is, neutral solutions) usually have a pH of 7. Acids have a pH that is less than 7. Alkalis have a pH that is greater than 7.
