Journal Entry:

What safety precautions should you consider today? How do you properly clean up after this lab?     

Learning Intentions

• You will understand precipitation reactions, learn how to write net ionic equations for such reactions and be able to identify the spectator ions in the reaction.

• You will learn to write a balanced net ionic equation for a chemical reaction they observe.

• You will learn how to test your predictions and explain any discrepancies between predictions and actual results.

Closing Task:

You can collect data for combinations of solutions, compare them to your predictions and explain any discrepancies.

Content Standards being covered:

LO 2.8 The student can draw and/or interpret representation of solutions that show the interactions between the solute and solvent.

LO 6.21 The student can predict the solubility of a salt, or rank the solubility of salts, given the relevant Ksp values.

LO 6.22 The student  can interpret data regarding solubility of salts to determine or rank, the relevant Ksp values.
