Describe the graph of pH values over the course of the reaction in Part II. Was the change in pH consistent over the course of the reaction? Do your best to explain the reason for the shape of the pH curve in your own words.
Why is it important to stir the solution in the flask as you add titrant from the buret?
If a student did not remove all of the bubbles from inside the buret before reading the initial volume and beginning the titration, will this cause the calculated concentration of the hydrochloric acid determined from that trial to be higher or lower than the actual concentration? Explain your answer in complete sentences.
Describe at least three possible sources of error in a titration experiment like this and, for each, explain whether the error would result in a calculated molarity that is too high or too low.

Consider this reaction involving an unknown element X. When 6.900 g of XBr reacts, 4.633 g of Br2 is produced. Calculate the molar mass of X.
The balloon rises in the atmosphere to an altitude where the pressure is 395mmHg and the temperature is -16.3 degrees C. Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.
The unknown compound assigned to a student was an aldehyde, but about half of the sample distilled around 65, and the rest of it distilled near 155?. (a) What is the name of the aldehyde. (b) What else was in the sample and why. Write a balanced e..
As you may well know, placing metal objects inside a microwave oven can generate sparks. Two of your friends are arguing over the cause of the sparking, with one stating that the microwaves "herd" electrons into "pointy" areas of the metal object,
