WebAt 25 0 C, summation of pH and pOH is 14. We use that relationship to determine pH value. pH + pOH = 14 pH + 2.88 = 14 pOH = 11.12 When ammonia solution is diluted by ten … WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution.
