Go to the following and review the lesson.
http://www.800mainstreet.com/acid_base/definitions-ph.html
Use the arrows on the top to progress through the pages titled:
  • Definition of pH, pOH, "p", sample calculations
  • Calculations of pH using a number line scale or calculator
Answer the following on a separate paper:
  1. If you know the concentration of [H+] of a solution in decimal form, explain how you can figure out its pH.
  2. As the value of the pH increases, what happens to the concentration of H+?
  3. As the value of the pH decrease, what happens to the concentration of H+?
  4. Solution A has a pH of 5. Solution B has a pH of 9.
    1. What is the [H+] of both solutions?
    2. Identify the solution as acidic or basic.
    3. Which solution has the greatest concentration of H+?

The conclusion portion should be completed and placed in front cover of portfolio.
 
If Absent:

Titration Make-up

Directions: Go to the following website http://tinyurl.com/7vosya5, then conduct the following procedure. Write at least one conclusion paragraph

 

Procedure:

1. Select "Weak Acid vs. Strong Base."

2. Fill Burette with "Base."

3. Click on step 3. From the slide out choose CH3COOH and NaOH

4. Choose Phenolphthalein.

5. Click on the slider next to the Burette to add about 30mL of Base. Notice that the solution in the flask is too pink.

6. Click on "Reset" and then repeat steps 1-4 again.

7. This time add about 18-19mL of the base using the slider.

8. Click on the dropwise button until the first time the solution remains pink.

9. Write down the following data:

  • Volume of Acid
    Molarity of Acid
    Volume of Base

10. Calculate the Molarity of the Base using the data above.

11. Type answer into Step 6 box and click ok. Record your results.

 

Conclusion: Claim (what is the objective of a titration), Evidence (State specific information that describes a titration), Reasoning (Why does titration work, explain in chemical terms)
