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).

A student began his careful titration with an air bubble in the buret tip. The bubble was released, unnoticed, before reaching the equivalence point on the titration curve. a) Predict the effect on the measured volume of NaOH added to reach the equivalence point. b) Predict the effect on the measured equivalence point pH value.

"In the weak acid titration, if you had not prepared your buret properly and a considerable amount of water was left in it, what would have been the effect on the calculated value of Ka?" I generally know that the Ka of an acid remains constant no matter what, but in this case, the Ka of the weak acid being titrated can be determined and is equal to the pH at half equivalence. How would a more dilute strong base...

Assume you have been working at your first job since college.. You now wish to buy a house for $450,000. You plan to make a 35 percent down payment while financing the rest. Assuming your neighborhood bank offers you a 30-year mortgage with a 4.50% interest rate, what will your monthly payments be? How would your monthly payments change if you increased your down payment to 50 percent?
