If the initial reading on a buret is 15.4ml and the final reading after titration is 27.2ml, how many ml of titrant was removed from the buret?

To find the amount of titrant that has been removed from the buret, you need to subtract the initial reading from the final reading. The initial reading is 15.4 ml, and the final reading is 27.2 ml.

The calculation is straightforward: Final reading - Initial reading = Volume of titrant used

So, 27.2 ml - 15.4 ml equals 11.8 ml.

This process is a fundamental aspect of titrations, where the change in volume indicates how much titrant has reacted with the analyte in a sample. The correctness of the answer, which is 11.8 ml, reflects the accurate measurement of titrant utilized during the titration process, essential for determining concentrations and analyzing the sample appropriately.
