Product Details
Classic AP Requirement #6—Standardization of a Solution Using a Primary Standard
Classic AP Requirement #7—Determination of Concentration by Acid–Base Titration, Including a Weak Acid or a Weak Base
In this three-part laboratory, a basic solution is first standardized against a known solid acid (KHP). This standardized base solution is then titrated against an unknown acid solution to determine the acid solution’s molarity. In the third part, the Ka of the solid acid KHP is calculated from the data of the titration curve obtained from plotting the pH of the solution versus the volume of NaOH solution added. The lab provides the recommended familiarity with the process of titration using indicators and pH meters.
Complete for 24 students working in pairs.

HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
