Unformatted text preview: initially started. After 120
minutes, take another 10mL aliquot and warm the solution to approximately 50°C for 10
minutes. Allow the solution to cool to room temperature and then titrate it. Record the volume of
NaOH used. This procedure was also done using 75% isopropanol in water mixture instead.
The observed amount of NaOH used to titrate the sample was used to calculate the t-butyl
bromide concentrations for any given time. Given the 1:1 ratio between NaOH and HBr, the
concentration of HBr at any given time can be calculated using equation 1: [HBr...
