Day 114: Water Dissociation


After our lab on pH we need to get down to the basics and figure out what pH is all about on an atomic and molecular level. We start with water dissociation and then the dissociation of acids and bases. Tomorrow we do the marshmallow activity to model acid/base dissociation.

Day 111: pH Lab


Today the IS II students were introduced to pH. We discussed properties of acids and bases and they used litmus paper to determine whether household items were acids or bases and then universal indicator paper to pinpoint the pH. Most enjoyed the activity and many had never used or heard of litmus paper.
