Journal Entry:

What are safety precautions we need to follow during this lab? How do we clean up at the end of class?
 

Learning Intentions

• We will learn what a precipitation reaction is.
• We will learn how to write both complete and net ionic equations for precipitation reactions and understand the difference.
• We will learn which ions tend to form precipitates and which tend to be spectators.
• We will learn how precipitation reactions can be used in the real world.

Closing Task:

You can write a net ionic equation for a precipitation reaction and identify the precipitate.

Content Standards being covered:

Student understands what the letters and numbers stand for in a compound formula, can use those letter and numbers to determine how many of each type of element there are in a formula.

Student can create mathematical representations of chemical reactions and use them to make calculations about products and reactants.

Students can use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. (HS-PS1-7 and CCC Energy and Matter)
