Objectives
1. Predict the product of an acid-base reaction.
2. Describe the conditions at the equivalence point in a titration.
3. Explain how you would select an indicator for an acid-base titration.
4. Describe the procedure for carrying out a titration to determine the concentration of
an acid or base solution.
Florida Sunshine State Standards Covered
SC.A.1.4.2
The student knows that the vast diversity of the properties of materials is
primarily due to variations in the forces that hold molecules together.
SC.A.1.4.4
The student experiments and determines that the rates of reaction among
atoms and molecules depend on the concentration, pressure, and
temperature of the reactants and the presence or absence of catalysts.
SC.C.2.4.5. The student knows that most observable forces can be traced to electric
forces acting between atoms or molecules.
