In this PLE we are going to continue our investigate acids and bases. (NOTE: If you can not answer a question below enter CNA.)

Give me some responses to the questions below and I'll give you some extra credit.

Laboratory Section:

1. Write an equation which describes how HCl(aq) behaves as an Arrhenius acid. Hint: Use only HCl(aq) as the reactant.)

2. Write an equation which describes how NaOH(aq) behaves as an Arrhenius base. Hint: Use only NaOH(aq) as the reactant.)

3. The bases we listed in class on Friday included NH3. This base looked much different compared to the other bases in the list. Yet it is a base because when it is added to water it increases the [OH-]. Complete the equation below to show how ammonia acts as a base;

NH3(aq) + H2O(l) --->

4. How does the chemical equation describing how NH3 acts as a base differ from the chemical equation describing how NaOH(aq) acts as a base?

5. A solution labeled 1.00 M HCl has a pH of 1.00. Explain how this observation supports the idea that HCl is a strong acid.

6. A solution labeled 1.00 M HC2H3O2 (acetic acid) has a pH of 2.37. Explain how this observation supports the idea that HC2H3O2 is a weak acid.

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