Acids, Bases and Reactions

ASSIGNMENT 1:

1. Watch the videos above on the historical development of what we know about acids and bases.

2. Create a double-bubble map comparing and contrasting the works of Arrhenis and Bronsted-Lowry in terms of their definitions of acids and bases.

ASSIGNMENT 2:

1. Play around with the lab above and test the pH of different substances.

2. Observe what happens to pH when you add water to the solution.

3. Write 3-5 complete sentences about your observations.

ASSIGNMENT 3:

1. Use the link above to complete the lab.

2. Write 10 complete sentence observations about acids and bases.

ASSIGNMENT 4:

1. Watch the videos above on how to make acid-base calculations.

2. Create a bubble map over acid-base calculations.

3. Then, get a copy of the acid-base calculation practice from me and use the videos to guide your calculations.

4. Remember, you are always welcome to ask questions. Just BE SPECIFIC! :)

ASSIGNMENT: SKIP

1. See me to complete a card sort with manipulatives.

2. Put them in order of pH and let me know when you are done.

3. Be prepared to explain your methods.

ASSIGNMENT 5:

1. Read the article above "Increasing Acid Could Kill Most Coral by 2050."

2. Imagine that you have been asked by the Australian Marine Conservation Society to create a proposal to stop the bleaching of the Great Barrier Reef caused by high levels of carbonic acid in seawater. Your proposal should include the following components:

• The chemical properties of carbonic acid including an explanation of the type of acid, degree of dissociation, and pH
• A detailed plan to stop the bleaching by chemical means including the chemical added to the sea water and the delivery method that will ensure the desired outcome
• A risk analysis that includes the products of the reaction used to reduce the amount of carbonic acid and the specific hazards to the ecosystem caused by the products

2. Organize your proposal so that it could be presented to the Australian Marine Conservation Society.
