Students experiment with acids and bases. For this elementary level chemistry lesson, students perform activities for testing acids and bases. They use universal indicator paper to determine which substances are acidic and which are bases. They perform an experiment with sherbet which contains both an acid and a base.
This video introduces students to the concept of Conjugate Acids and Bases. The important point for students to grasp, and Sal does a nice job illustrating this point, is that for every conjugate acid/base pair, the weaker the acid, the stronger its base will be. The weaker the base, the stronger its conjugate acid will be.
A variety of skills are needed to complete this assignment. Strong acids and bases are to be described using the Arrhenius model, balanced equations written and analyzed for acid dissociations, and then concentrations calculated for different solutions. This learning exercise will come in handy for you to give as homework or as a review in your advanced chemistry course.
Young chemists analyze Titration curves as part of this acids and bases worksheet. Other problems include calculating concentrations, determining equilibrium constants, and a few multiple-choice questions. Since this resource uses a variety of question types, you could use it as a quiz.
An encompassing set of notes is presented throughout most of this worksheet. Topics covered are the nature of acids and bases, calculating the acid dissociation constant, and acid/base strength. The worksheet concludes by having young chemists perform dissociation constant calculations. It is a valuable reference sheet and practice for your class.
