Question

Suggest reasons why your experimental values might be higher or lower than the literature values. Thank you! 3. Suggest reasons why your experimental values might be higher or lower than the literature values. Possibilities may include: a. You added several mL of acid at a time, rather than adding acid drop-by-drop as you approached the equilibrium point. beginning of the titration. acid (vs. a base with an acid), because... b. A trace of acid impurity may have been present in the Erlenmeyer flask at the c. It may have been more difficult detecting the endpoint when titrating a base with an

Explanation / Answer

(a) Higher value. This because when we add several ml of acid at a time instead of drop-wise then there is high possibility that we ended up having excess acid. So we will calculate that if more acid is used mean that there was more amount of base present.

(b) Lower value. This is because if any acidic impurity will be there then it will already neutralize some amount of the base as a result less volume of acid will be used to reach the end point. On calculation it will give that lesser base was present than the actual.
