WebbThere is an important inverse relationship between pH and pOH in that pOH values greater than 7 define solutions that are acidic! This is the result of the sum: pH + pOH = 14. Using this expression, one can determine the pOH if the pH is known. A solution at pH 5.5 would thus have a pOH of 8.5. Webb13 apr. 2024 · The TAs for the samples were measured using a single-point spectrophotometric titration method with bromocresol purple (BCP). Throughout each titration, the pH of each sample was continuously monitored by measuring the absorbance ratio (R) of the basic/acidic forms of BCP as the titration work was in progress.
