Next time:
Lab: “Solubility Product Constant”
Please dress appropriately
“Solubility Product Constant”
Purpose
The purpose of this lab is to:
Prepare a saturated solution of NaCl.
Calculate the concentration of each ion in
the solution.
Write an equilibrium expression and
calculate the Ksp of NaCl. (?)
Demonstrate the effect of adding a
common ion to the saturated NaCl solution.
Calculate the mass of NaCl necessary to fill
a vat with 4,000 L of saturated solution.

ACT Prep
Science Workouts “F” and “E”
Science Workout “F”
You will have 20 minutes to answer 22
questions.
Please DO NOT WRITE on the tests, I only have
a class set. Use a separate piece of paper to
record your answers.
After 20 minutes, grade your own using the
key. Review any questions you missed.
