WebApr 9, 2024 · The pH scale is the measurement of how acidic or basic a substance is. It specifically measures the amount of free hydrogen ions found in a solution. Although it sounds contradictory, substances with a low pH (below 7) have more free hydrogen ions and are considered acids. WebCalculate the unknown molarity of the diluted acetic acid from the volumes of acid and base at the equivalence point and the molarity of the NaOH M a × V a = M b × V b. 3.b. Once you find the molarity of your diluted solution, use that to calculate the molarity of the original solution using the equation M 1 × V 1 = M 2 × V 2 a second time. 4.
