PPT-Double Indicator Titration

Inorganic LabBSc III Sem Object To determine the strength of NaOH and Na 2 CO 3 mixture in the supplied solution by Acid Base Titration Methyl Orange Phenolphthalein Materials Required. The percentages of each individual indicator are z score transformed A Z score transformation is achieved by subtracting the mean of the distribution from the variable value and dividing the difference by the standard deviation of the distribution Z Learning Goal 25 Calculate the pH at any point, including the equivalence point, in an acid-base titration. At the equivalence point, the pH = 7.00 for strong acid-strong base titrations. However, in Lab 10. Outline. Purpose. Potentiometric. Titrations. Proticity. Equivalence. pK. a. Vinegar Titration.
