It is OK to use your textbook or lecture notes from class, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

First Name:

Last Name:


1. Write the reaction that occurs when HCl(aq) is added to a solution of NaOH(aq).

2. If 200.0 mLs of 0.250 M HCl is added to 150 mLs of 0.275 M NaOH, which of the two reactants is the limiting reagent? HCl or NaOH?

What evidence do you have to support your claim?

3. Calculate the moles of NaCl produced in the reaction in Q2.


4. Calculate the concentration of NaCl in the resulting solution. (Assume the volumes of the two solution are additive when mixed together.)


5. Calculate the concentration of the reactant that is in excess after the reaction goes to completion.


6. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

7. If there is one question you would like to have answered in lecture, what would that question be?
