WebbMeasured on a scale of 0-14, solutions with a pH of less than 7.0 are acids while solutions with a pH of greater than 7.0 are bases. In very simple terms bases are used to neutralize acids, while acids are used to neutralize alkalis (the term caustic, alkaline, alkali, or base, although not truly synonymous, are often used interchangeably ).
