AgendaLab write-up: “Solubility Product Constant”ACT Prep Concept Review Work Time

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.

the bunsen burner, NOT the hot plate optionProcedureReflection Statement

Remember to update your table of contents…

ACT PrepScience 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.

Look on the back page of the test to find your estimated ACT Science Score and record it on your paper.

ACT PrepScience Workouts “F” and “E”

Science Workout “E”You will have 16 minutes to answer 18

questions.You can use the same piece of paper for your

answers.Complete same as Workout “F”.

Please turn in your paper with answers/estimated scores for a participation grade.

Concept Review Work TimeAny additional time can be well spent by working

on the concept review.
