SWBAT describe how acids and bases can conduct electricity by watching a video.

SWBAT sort properties of acids and bases by using a Venn Diagram.

Essential Question What are the properties and examples of

acids and bases?

Objectives

Electric Pickle How does it work

◦ Strong/weak acids/bases

Electric Pickle Experiment

All acids and bases do not ionize or dissociate to the same extent. This leads to the statement that acids and bases are not all of equal strength in producing H+ and OH- ions in solution. The terms "strong" and "weak" give an indication of the strength of an acid or base. The terms strong and weak describe the ability of acid and base solutions to conduct electricity. If the acid or base conducts electricity strongly, it is a strong acid or base. If the acid or base conducts electricity weakly, it is a weak acid or base.

In the folder you will have a list of 25 properties and examples of acids and bases.

You also have a reading about acids and bases.

Make a Venn Diagram on a sheet of lined paper and write down all 25 statements◦ You should make a list of the 25 statements and

put the numbers in the Venn Diagram You may work with the people at your table
