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

SID#:

Laboratory Section:

1. In the following equation, label the acid, base, conjugate acid and conjugate base;

NH3(aq)

+

HNO3(aq)

--->

NH4+(aq)

+

NO3-(aq)

 

 

 

 

2. Based on the chemical equation in Q1 what are the two conjugate acid/base pairs? Write the pair using the following formate....acid/base.

3. What is the difference between an acid/base conjugate pair?

4. Using the chemical equation in Q1, and knowing that K is very large, identify the strongest acid and the strongest base in the equation.

You are given a solution with the label 0.500 M formic acid (HCOOH).

5. Is the concentration of HCOOH in the solution actually 0.500 M? Explain.

6. Write a chemical equation which describes how formic acid behaves as an acid.

7. The pH of the 0.500 M HCOOH solution is 2.02, calculate the [H+] in this solution. Based on the calculation, what can you conclude about the strength of formic acid?

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