Errors in experimental procedures. Assume the volume of base in the buret was not at the 0.00 mL mark when you began the titration for benzoic acid. How might this have affected your results? Your results would not be affected if you subtracted the final titrant volumefrom the correct initial titrant volume You may have recorded less titrant added than you actually used You may have recorded more titrant added than you actually used Your results would not be affected if you subtracted the final titrant volumefrom the correct initial titrant volume and you may have recorded more titrant added than you actually used The concentration of titrant would more than recorded

Explanation / Answer

Answer:

Your results would not be affected if you subtracted the final titrant volume form the correct initial titrant volume. Because if the initial reading is below the 0.0 mLmark(0.5,1.0, 1.5mL etc) more titrant will be recrded than actual. If the initial titrant is above the 0.0 mL mark, less titrant will be recorded than actual.
