1) Assume an air bubble had been in the buret tip when you took your first reading and it was replaced by NaOH during the course of the titration. Would your experimental value for the concentration of NaOH be too high, too low, or unchanged as compared to the true value? Explain
2) Assume the buret had been wet with water because it was not adequately rinsed with base. Would your experimental value for concentration of NaOH be too high, too low, or unchanged as compared to the true value? Explain
3) Using your calculated concentration of NaOH from lab how many grams of KHP would you need to start with in order to have an end point at 35.00 mL?
4) If 0.839 g of KHP were titrated, and 34.58 mL NaOH solution were necessary to reach the equivalence point, what is the concentration of the NaOH solution? (Make sure to report the correct number of significant figures).
