The Charge of the Proton! It's ENERGY, it's ACTION, it's Something Happening!

So...my computer is currently uploading a video message from me, but it is going slow, and I don't know how it will turn out...wait>>>IT WORKED!  A new era dawns!  Imagine the possibilities; I can talk to you about yesterday's experiment or try again to explain a difficult concept!  WOWsers.

So, good work, ladies, on your lab.  Young men, your groups could use an upgrade in cooperation and also in reading the directions.  If you have not done last week's homework, or understood it poorly, please re-read chapter 25, section 2, particularly pages 772-774 (just 3 pages!)  If you did last week's homework and understood it, then it's an easy read and a great warm-up for today's homework, which is this:

Today's Homework:
1. pHet simulation: https://phet.colorado.edu/sims/html/acid-base-solutions/latest/acid-base-solutions_en.html  THOROUGHLY explore this simulation, using all the Solutions and Tools, first in the Introduction and then in My Solution, - figure out how the sim works and then learn from it.

• When you do the My Solutions page >>> MAKE A TABLE, like this: https://drive.google.com/file/d/0B07s3-bcUr7tYS1Lcl9jdkFFaHM/view?usp=sharing
• 
  
• Change the acid/base concentrations and strengths
• dip the pH meter in the water, dip the litmus paper, use the light bulb to test conductivity 
• notice the chemical equation, what does HA mean, etc./ (H is H+ and A represents acid) MOH? M represents the metal ion and OH is OH-.  Notice that a strong acid uses a one-direction arrow and a weak acid uses arrows going in both directions.  What does this represent?  Notice the differences in the diagram as you switch from strong to weak acid.  

2.  A really excellent 30 minute video deserving the full concentration (and strength) of your attention:

• Acids and Bases: The Voyage of the Proton   Don't forget to pound it into your brain: H+ is a proton, so pH is the Power of the Proton, it has a charge, and a charge is like a battle cry, Charge! It's energy, it's action, it's Something Happening!
