While I'm Away...

Goals:

• Describe how to operate a spectrophotometer to find  λmax and absorbance values of a given solution. 
• Define concentration in terms of solute, solvent, and solution. 
• Perform calculations using  C=m/V.
• Calculate the concentration of a dilution using C1V1=C2V2.

This blog post will be your go to guide for Wednesday-Friday
Over the course of the 3 days, you will need to complete the 2 assignments below (I also wrote a note on the whiteboard).


ASSIGNMENT 1: SPECTROPHOTOMETER TUTORIAL
Work with your elbow partner to create a tutorial. Here are some resources:

• Tutorial Guidelines - This is Process Artifact 1
• User Manual
• WikiHow

ASSIGNMENT 2: CONCENTRATION CALCULATIONS
Complete pages 8-13 of the packet.

1. Go through the slides on your own and use them to complete the notes on pages 8-10 and 12 in the packet. 
2. Complete the practice problems on pages 11 and 13 of the packet. 
3. Check your answers on the answer key I left with the sub. 

EARLY FINISHERS
Should do academic recovery to clear NMs or study for upcoming competencies.

How Specs Work
Using the video below and instruction from Mrs. Wallace, complete the notes section on page 5 of your packet.


Practice
Read page 6 and complete page 7 of the packet using the provided solutions.
*EDIT* Change "Green" solutions to "Blue"
When you have finished, check your measurements for accuracy with me.

Tutorial
If you finish early you can begin making your tutorial (Process piece for your badge).

Spectrophotometry Basics

Solutions and Spectrophotometry Packet - Open in Notability

Warmup
Grab a whiteboard. With your table, draw a diagram to explain how we see the color blue.

Notes
We will go through page 2 of the packet as a class.

Beer's Law Phet
Use the Beer's Law Phet simulation to complete pages 3-4 of the packet.
