Activities
- This "Acid and Base"
worksheet from Mr. Guch's Calvacade
of Chemistry uses the Brønsted-Lowry
theory of acids and bases.
- Mr. Guch provides these worksheets
for practice with pH: "pH Practice" , "pH Calcuations"
 ,
and "pH Review Problems .
All Mr. Guch's worksheets include answers.
- Dr. Greenbowe has a "Solutions of Acids, Bases,
and Salts" simulation that allows students to
use a pH meter to test solutions of various acids and bases at
differing molarities. He also has an accompanying tutorial with worksheet.
- Try this pH
Scale online activity that has students place common
household products in the correct order according to their pH.
- For practice with molarity, try Mr.
Guch's "Molarity Practice Problems"
and "Molarity Calculation" worksheets.
- Dr. Greenbowe's "Determining of the Molarity of an
Acid or Base Solution" simulation is also accompanied with
a tutorial with activity.
- On the lighter side, do this online "Acid Rain" crossword puzzle or this "Acids, Alkalis, and Salts" online
crossword.
- These exercises on "Buffers and Acid-Base Titrations"
are accompanied by links to background information and solutions to the
problems.
- Play this online "Ph
and pOH" game.
- Dr. Greenbowe's "Buffered Solution" simulation is accompanied by this activity.
- Have students do this printable "Acids and Alkali" crossword
puzzle with answers. The author tells you to set your printer options to
print the background. To do this, select "Tools" in your
browser, then "internet options", select the "advanced" tab and scroll
down to "Printing" and place a check in the box, "Print background
colors and images."
- The ChemCollective offers this
problem set on "Acid Base Chemistry and Buffers."
- Mr.
Guch's site also this "Dilutions Worksheet" and this "Intermolecular
Forces" worksheet.
- Have students do this "Acids, Bases, and
pH" wordsearch puzzle with
answers .
- "The Basics of Acids and Bases" is a
comprehensive WebQuest for students that includes an evaluation rubric.
- Use the "GEMS Alien Juice Bar" to complete
the "GEMS Alien Juice Bar Activity" .
- Try this "Acids and Bases"
crossword puzzle with answers.
- Vanderbilt
Student Volunteers for Science have created this
whole unit, "pH ," to introduce students to acids,
bases, and the pH scale.
Labs
- Prepare your indicator using red cabbage in this
"Making a pH Indicator"
lab. Then, try this "Cabbage Juice Indicator pH" lab. Use this color
chart.
- Demonstrate pH with the reaction between the
hydrogen ion and hydrogen carbonate ion in this "pH:
It' a Gas" demo.
- Do this colorful "Acid and Base Demonstration."
Several companies offer kits called "MOM to the Rescue:" that work
similarly to this.
- Do this "Testing the pH of Oxides"
lab.
- Another pH testing
lab.
- Test these text book style strong acid and base
problems using ChemCollective's "Virtual Lab."
- Have fun with the "Disappearing Ink" lab.
- Try this "Metals and Acids"
using sulfuric acid and zinc.
- Do this "Titration of Sodium Hydroxide With
Hydrochloric Acid" lab.
- Or do this micro-scale "Titration of Vinegar" lab to
determine the amount of acetic acid in a sample ofvinegar.
- Do Flinn's "Disappearing
Rainbow" demonstration where a rainbow of
solution colors appear and disappear as acids and bases are added to a
series of indicators.
- To see if student's have properly cleaned up their
lab area, do Flinn's "The Indicator
Sponge" demo.
- Try Flinn's "Water to Grape
Juice to Milk" acid-base demonstration.
- Do Mrs. J's "Household Acids and Bases
Lab" .
- Do Flinn's "Orange
Juice to Strawberry Float: A Foamy Acid-Base Demonstration" .
