Principle
The Cobra SMARTsense pH (alternatively the Cobra SMARTsense Dropcounter with a pH-electrode) is utilized to determine the pH value of the weak acid. The solution of a strong base with known concentration (here: sodium hydroxide, 1 M) is filled into the burette. The base is added in 1 ml steps to the acid, the pH value will be determined after every step. The equivalence point is determined with a suitable indicator (here: phenolphthalein).
