Question
Suppose your instructor mistakenly gave you a sample of "KHP" contaminated with an inert solid for use in standardizing your NaOH. What effect would this have on the calculated molarity of the NaOH? Explain. If the endpoint in the titration of "KHP" with NaOH is mistakenly passed (too pink), what effect (high, low, no effect) does this have on the calculated molarity of the NaOH? Explain your choice. If the "KHP" was not completely dissolved before titrating with NaOH, what effect (high, low, no effect) would this have on the calculated molarity of the NaOH? Explain your choice.Explanation / Answer
Q1.
If this has inert material, then the mass of KHP is not 100% KHP, so there will be LESS neutralization per unit mass
meaning, that twe will require more MASS than in reality
So the concentration of NaOH will appear to be higher, than it really is
Q2.
If we passed by too much titrant, then the volumew ill be largen than reality, this will implie higher amount of moles of NaOh than reality, i.e. more concentration of NaOHJ
Q3.
if not all KHP dissolves, then concentration of KHP is lower than in reality, meaning that we require more KHP than it really is
so concentration of NaOh will appear higher
