Conjugate Acids and Bases

IQ2: What is the role of water in solutions of acids and bases?

Students:

● conduct an investigation to demonstrate the use of pH to indicate the differences between the strength of acids and bases

● construct models and / or animations to communicate the differences between strong, weak, concentrated and dilute acids and bases

● write ionic equations to represent the dissociation of acids and bases in water, conjugate acid/base pairs in solution and amphiprotic nature of some salts, for example:

– sodium hydrogen carbonate

– potassium dihydrogen phosphate
