Acids Bases in Cooking Livestrong

An acid is a solution with a value between 1 and 6.99 on the pH scale, a chemical gauge of acidity and alkalinity that goes from 1 to 14. A base is a substance with a pH value greater than 7. Bases are termed "alkaline," meaning that they neutralize acids. Water, which has both acid and base, is considered chemically neutral, having a pH of 7.
