Daisia Frank CHEM 1121 Dr. Reed July 31, 2016 Determining the Identity of an Unknown Weak Acid Lab Report Introduction: In this experiment, a weak acid’s identity was determined using the method of titration for weak acids. The titration was performed with standard sodium hydroxide solution. In order to do this, the titration had to be monitored by an indicator or pH meter. A pH meter and LoggerPro software on a computer were used to determine the equivalence point of the titration. Buffer Region a Equivalen ce Volume
