Final answer:
To calculate the titer, subtract the initial burette reading from the final burette reading. The titer represents the volume of the solution delivered during a titration and is used to determine the concentration of the analyte. It's important to use stoichiometry and the volume of titrant solution in calculations.
Step-by-step explanation:
To calculate the titer, we need to subtract the initial burette reading from the final burette reading. In this case, the final burette reading is 28.45 mL and the initial burette reading is 5.60 mL. So, the titer is calculated as 28.45 mL - 5.60 mL = 22.85 mL.
The titer represents the volume of the solution that has been delivered from the burette during a titration. It is used to determine the concentration of the analyte in the solution being titrated. In this case, the titer represents the volume of the titrant solution (the solution in the burette) that has reacted with the analyte solution (the solution in the flask).
It's important to note that the titer is specific to the particular titration and may not have a direct relationship to the concentration of the analyte solution. The titer is used in calculations to determine the concentration of the analyte solution based on stoichiometry and the volume of titrant solution used in the titration.
