Title: M4 - The Big Picture - pH
Course: Open PRO130 Instrumentation I > Section: Module 4: PROCESS VARIABLES, ELEMENTS, AND INSTRUMENTS: LEVEL & MISCELLANEOUS MEASURING DEVICES

This module we will cover the information in Chapters 6 & 7  in your textbook in class. Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

Other goals:

- Determine if a solution is acidic or basic
- Place acids or bases in relative order
- Describe on a molecular scale, with illustrations,
how the water equilibrium varies with pH
- Determine concentration of hydroxide, hydronium
and water at given pH
- Relate liquid color to pH
- Predict (qualitatively and quantitatively) how dilution
and volume will effect the pH and concentration of hydroxide, hydronium and water

Important Notes:

- If you need some help with how to manipulate the controls, see the Tips for controls sheet.
- If you do not see a simulation above, go to this page at the PhET website
- You must have Java updated on your computer in order to run the simulations.
