Question: A student dossolves 0.25g of KHPh in 0.050 L of water while performing an acid and base titration to determine the [ ] of a KOH solution. The student washed down the sides of the flask with 5 mL of deionized water, but did nto include that volume in the total volume. Why is it not necessary to record the exact amount of water used to make the solution?
Here is my answer, which my teacher told me was wrong somewhere.
It is not important because al that matters is the measure on the buret - where the titrant starts and where it ends. For instance, when I did this lab before, I took the difference between the two measurements to figure out how much titrant I used. What the student should do is not add any more titrant in the buret which would alter the measurement.
