Carolina Investigations® for AP® Chemistry: Complexometric Titration of Calcium in Milk Kit

Item # 840572 Exclusive

Addresses AP® Chemistry Big Idea 1 and Learning Objective 1.20. Students determine the concentration of calcium in milk by complexometric titration, either by preparing and standardizing a solution of EDTA and using it to determine the concentration of calcium in milk, or by designing a procedure to collect and analyze data, perform error analysis, write and balance chemical equations, use volumetric glassware, standardize a titrant, and perform multiple trials. For 30 students in teams of 3.

$49.95

In stock and available to ship.

  • Aligned with Big Idea 1 and Learning Objective 1.20
  • Emphasizes Science Practices 2, 3, 4, 5, 6, and 7

Determine the concentration of calcium in milk by complexometric titration. Teach this laboratory experience using either the guided activity or inquiry activity. In the guided activity, students prepare and standardize a solution of EDTA and use it to determine the concentration of calcium in milk. Both the standardization and sample titrations are done 3 times and the average of the values used in the calculations. The inquiry activity allows students to design a procedure to determine the concentration of calcium in milk and requires them to account for interfering substances such as magnesium and other transition metals. The inquiry activity provides an opportunity for students to present their experiment design and results, reinforcing the practice of communicating findings. Detailed preparation and procedure notes guide the teacher through leading a successful inquiry exercise, including a suggested rubric for assessing student performance.

Both activities include Big Idea assessment questions that follow the format of the AP® Chemistry Exam free-response questions. In the Big Idea assessment, students consider another complexometric titration, the titration of zinc in zinc lozenges with EDTA, and calculate the concentration of zinc in the lozenge based on data provided. They also are required to consider what to do if they forget to standardize their titrant before they titrate the zinc.

Provides the following AP® Chemistry experiences: design a procedure to collect data, analyze data, perform error analysis, write and balance chemical equations, use volumetric glassware, standardize a titrant, and perform multiple trials. Analyzing calcium in milk engages students and makes the concepts covered more interesting. Materials are sufficient for 30 students working in teams of 3. Digital teacher’s manual, included FREE with kit purchase, is a 12-month eBook license to the Complexometric Titration of Calcium in Milk teacher’s manual. You can also access the digital student guide for this kit for free at Carolina Science Online®.

Carolina Investigations® for AP® Chemistry: Kits That Support the AP® Curriculum

Carolina Investigations® for AP* Chemistry Kits

If you are an AP® teacher, you go out of your way to help your students perform successfully on the AP® Exam. Carolina Investigations® for AP® Chemistry Kits are specifically designed to help you do just that.

Carolina Investigations® for AP® Chemistry kits are specifically designed to meet the goals of the revised AP® Chemistry curriculum. That curriculum and our kit series center on 6 overarching BIG ideas, which provide the themes for an enhanced laboratory experience focused on inquiry-based, student-directed learning:

  • Big Idea 1: Atoms
  • Big Idea 2: Chemical and Physical Properties
  • Big Idea 3: Changes in Matter
  • Big Idea 4: Rates of Chemical Reactions
  • Big Idea 5: Thermodynamics
  • Big Idea 6: Chemical Equilibrium

The AP® Chemistry curriculum emphasizes science practices, which allow students to use the tools of scientists to discover, test, and explain natural phenomena. The science practices of AP® Chemistry are integrated into each lab in the Carolina Investigations® for AP® Chemistry series.

  • Science Practice 1: Modeling
  • Science Practice 2: Math
  • Science Practice 3: Scientific Questioning
  • Science Practice 4: Data Collection
