What precautions should be taken when conducting the chloride test in boiler water?
Consider a titration where 0.215 M potassium hydroxide is added from a burette to 10.00 mL of hydrochloric acid in an Erlenmeyer flask under the burette. A few drops of phenolphthalein are added to the acid in the Erlenmeyer flask. Discuss how the pH of the solution in the Erlenmeyer flask changes as the titration is carried out. Your response should focus on the pH at the beginning of the titration (before the addition of any base), the pH at the equivalence point, and the pH past the equivalence point.
