A solution is to be standardized by titrating it against a known mass of potassium hydrogen phthalate. Which procedure will give a molarity of that is too low?
View answer and explanation
Correct option: C
Neglecting to fill the tip of the buret with
solution before titrating
solution before titrating
Option C (Neglecting to fill the tip of the buret with solution before titrating) is correct because it results in a smaller volume of NaOH being used than recorded.
